An equation is an equality between two expressions that contain one or more variables. The expressions on the left and right side of the equal sign are called the left and right members, respectively. Equations can have one or multiple variables, and they can involve operations like roots, powers, logarithms, etc. Resolving an equation means finding the value or values that satisfy the equality. The narrator also emphasizes that it's important to distinguish between expressions and equations, as equations are the only ones where operations like adding or subtracting can be performed.**00:10:00**In this section, the video explains that equations with multiple variables are not commonly worked on, and most equations typically have one or two variables. The goal of solving an equation is to find the value(s) of the variable(s) that make the equality true. The video starts by demonstrating how to solve equations with one variable, showing examples where the solutions can be found mentally. The instructor emphasizes that the important part is finding the correct answer, regardless of the method used. The video then progresses to more challenging equations later on.**00:15:00**In this section, the video discusses solving equations of the first degree. It explains that these equations may not be easy to solve mentally, so certain procedures are used to find the answers more easily.

The first strategy is to replace the variable with a number that satisfies the equation. The video provides examples to illustrate this strategy. The second strategy is called "despejar la variable," which means isolating the variable. The video discusses three properties of equality that are useful in solving equations: the symmetric property, the additive property, and the multiplicative property. Understanding these properties helps in manipulating equations to isolate the variable.**00:30:00**In this section, the speaker discusses the properties of equations and demonstrates how to apply them to solve for variables. They explain that if two expressions are equal, then adding or subtracting the same number to both sides of the equation will still yield an equal result. They emphasize the importance of understanding these properties when solving equations and provide examples to illustrate their use. The speaker also introduces the concept of finding the additive opposite of a number and using it to remove a constant term from an equation. Overall, this section provides a foundation for solving first-degree equations.**00:35:00**In this section, the speaker explains how to solve equations of the form x + a = b. They demonstrate this by using an example equation where x + 3 = 12. By subtracting 3 from both sides of the equation, they obtain x = 9 as the solution. The speaker also introduces the concept of adding the opposite additive to both sides of the equation to isolate x. They apply this to an equation x - 1/2 = 2, and by adding 1/2 to both sides, they determine that x = 5/2. They emphasize that this method simplifies the process of solving equations and invite the viewer to try it on their own. Lastly, the speaker provides another example equation x - 5 = 8 and explains that by subtracting 5 from both sides, they obtain x = 3 as the solution.**00:40:00**In this section, the video explains a strategy for solving equations of the form 'x = a + b' or 'x = a - b' by moving the coefficient of b to the other side of the equation with the opposite sign. For example, in the equation 'x = 8 - 5', the video suggests moving the +5 to the other side as -5, resulting in 'x = 8 - 5'. The video also introduces the property of multiplying or dividing both sides of an equation by the same number, which creates another equal equation. This property is especially useful when the variable x is being multiplied or divided by a number instead of being added or subtracted. To illustrate this, the video provides an example of multiplying both sides of the equation '2 + 1 = 3' by 3, which results in '9 = 3 + 3'. Finally, the video explains how to apply this property to equations like '3x = 21', by dividing both sides of the equation by the coefficient of x. The video concludes by demonstrating the application of these strategies to more complex equations.**00:45:00**In this section, the speaker discusses various strategies for solving equations of first degree. They explain that if a number is being added to the variable, it can be changed to subtraction, and if a number is being subtracted, it can be changed to addition. Similarly, if a number is being multiplied, it can be changed to division. These strategies help simplify the equations and make them easier to solve. The speaker then provides examples of equations and demonstrates how to use these strategies to find the value of the variable.
