Ответ:

$3 - 4x = 3(y + 1) \\ 2(x + y) = 5y + 8 \\ \\ 3 - 4x = 3y + 3 \\ 2x + 2y = 5y + 8 \\ \\ - 4x - 3y = 0 \\ 2x - 3y = 8 \\ \\ 4x + 3y = 0 \\ 2x - 3y = 8 \\ \\ 6x = 8 \\ x = 1 \frac{1}{3} \\ 2 \times 1 \frac{1}{3} - 3y = 8 \\ - 3y = 8 - \frac{8}{3} \\ - 3y = 5 \frac{1}{3} \\ y = - \frac{16}{9 } \\ y = -1 \frac{7}{9}$
