Question

Решите уравнение: 2x+2+3(x+4)=-4(1-x)+3

Answer 1

Объяснение:

$2x + 2 + 3(x + 4) = - 4(1 - x) + 3 \\ 2x + 2 + 3x + 12 = - 4(1 - x) + 3 \\ 5x + 2 + 12 = - 4(1 - x) + 3 \\ 5x + 14 = - 4(1 - x) + 3 \\ 5x + 14 = - 4 + 4x + 3 \\ 5x + 14 = - 1 + 4x \\ 5x + 14 - 4x = - 1 \\ x + 14 = - 1 \\ x = - 1 - 14 \\ x = - 15$
