Answer 1

$- 8x + 4(7 + 8x) = 4x + 7 \ - 8x + 28 + 32x = 4x + 7 \ - 8x + 32x - 4x = 7 - 28 \ 20x = - 21 \ x = ( - 21) div 20 \ x = - 1.05.$
Ответ : х = -1,05.

Удачи))))

Answer 2

$- 8x + 4(7 + 8x) = 4x + 7 \ \ - 8x + 28 + 32x = 4x + 7 \ \ 24x + 28 = 4x + 7 \ \ 24x - 4x = 7 - 28 \ \ 20x = - 21 \ \ x = - frac{21}{20} = - 1 frac{1}{20}$
