Question

(2x-6)-(6x-10)=2(4x+10).

Answer 1

Ответ:

$x = - \frac{4}{3}$

Пошаговое объяснение:

$(2x - 6) - (6x - 10) = 2(4x + 10) \\ 2x - 6 - (6x - 10) = 2(4x + 10) \\ 2x - 6 - 6x + 10 = (4x + 10) \\ 2x - 6 - 6x + 10 = 8x + 20 \\ - 4x - 6 + 10 = 8x + 20 \\ - 4x + 4 = 8x + 20 \\ - 4x + 4 - 8x = 20 \\ - 4x - 8x = 20 - 4 \\ - 12x = 20 - 4 \\ - 12x = 16 \\ x = - \frac{4}{3}$
