[tex] \frac{4x + 7}{2} = \frac{2x + 2}{3} \\ 3(4x + 7) = 2(2x + 2) \\ 12x + 21 = 4x + 4 \\ 12x - 4x = 4 - 21 \\ 8x = - 17 \\ x = - \frac{17}{8} \\ x = - 2 \frac{1}{8} \\ x = - 2.125[/tex]

Пошаговое объяснение:

(4х + 7)/2 = (2х + 2)/3

2(2х + 2) = 3(4х + 7)

4х + 4 = 12х + 21

4х - 12х = 21 - 4

-8х = 17

х = 17 : (-8)

х = -17/8

х = -2 1/8
