Question

Решите, пожалуйста, уравнение:2x-3/8 + 1-5x/6=3​

Answer 1

Ответ:x = 2 + 1/28

Объяснение:

2x = 48x/24

3/8 = 9/24

1 = 24/24

5x/6 = 20x/24 =>

2x - 3/8 + 1 - 5x/6 = 48x/24 - 9/24 + 24/24 - 20x/24 = 3

24/24 - 9/24 = 15/24 =>

48x/24 - 9/24 + 24/24 - 20x/24 = 48x/24 + 15/24 - 20x/24 = 3

48x/24 - 20x/24 = 28x/24 =>

48x/24 + 15/24 - 20x/24 = 28x/24 + 15/24 = 3

3 = 72/24 =>

28x/24 + 15/24 = 3 = 72/24

т.е. 28x/24 + 15/24 = 72/24 => 28x/24 = 72/24 - 15/24

72/24 - 15/24 = 57/24 = 2 + 9/24

28x/24 = 2 + 9/24 =>

28x/24 * 24 = 28x = 2 * 24 + 9/24 * 24 = 48 + 9 = 57

т.е. 28x = 57 =>

28x / 28 = x = 57/28 = 2 + 1/28

т.е. x = 2 + 1/28
