Question

Решите!!!
(3x - 8) / 2 = -1
x/4 - (x - 3)/5 = -1

Answer 1

1)
$\frac{3x - 8}{2} = - 1 \\ 3x - 8 = - 1 \times 2 \\ 3x - 8 = - 2 \\ 3x = - 2 + 8 \\ 3x = 6 \\ x = 2$
Ответ: 2
2)
$\frac{x}{4} - \frac{x - 3}{5} = - 1 \\ 5x - 4(x - 3) = - 20 \\ 5x - 4x + 12 = - 20 \\ x + 12 = - 20 \\ x = - 20 - 12 = - 32$
Ответ: -32
