Ответ:

$4.5x - \frac{2}{3} \times (8x - 10) = 4 - 2x \\ \frac{9}{2} x - \frac{16}{3} x + \frac{20}{3} = 4 - 2x \\ 27x - 32x + 40 = 24 - 12x \\ - 5x + 12x = 24 - 40 \\ 7 x = - 16 \\ x = - \frac{16}{7}$

Пошаговое объяснение:

4.5x - 2/3*(8x-10)=4-2x

9/2*16/3+20/3=4-2x

27x-32x+40=24-12x

-5x+40=24-12x

-5x+12x=-40+24

7x=-16

X=-16/7
