00:00:00 - 00:10:00

This video explains how to solve equations of first grade with fractions by changing the fractions to integers and multiplying all terms of the equation by the number that eliminates the denominators. The final step is to simplify the result.

• 00:00:00 In this video, an explanation is given of how to solve equations of first grade with fractions, using the example of solving for x in the equation 3x + 10 = 20. The method used is to change the fractions to integers, and then multiply all terms of the equation by 4, which is the number that eliminates the denominators. This example shows how to simplify an equation with fractions by canceling out the same number in the numerator and denominator.
• 00:05:00 In this video, Steps 1-4 from the previous video are explained in more detail. The final step is to simplify the result, which is 21 divided by 3.
• 00:10:00 This video explains how to solve equations of first grade with fractions. First, x equals 26 over 26 and this is 1. Next, the equation becomes x equals 1. Finally, the students are given an exercise to practice solving this equation. The answer appears at 3, 2, 1. First, the common multiples of 4 and 8 are multiplied together to get 2, 4, 8. Then, these numbers are simplified by adding 2 and 8, and the result is 2. Next, 25 is multiplied by 8 and 6 is added to the left side. The 5 on the right side becomes negative, but the 16 on the left side remains the same. The 6 that was originally positive becomes negative, and the sign changes on the 6. The 5x is multiplied by 16 and the result is 10. The 5 is multiplied by 5 and the result is 2. The 10 is divided by 5, which is 2. The equation is solved by multiplying x by 2 and the result is 2.
