Answer 1

Ответ:

$13x + 25 = 12x + 14 \\ 13x - 12x = 14 - 25 \\ x = - 11$

$8y - 13 = 12y - 9 \\ 8y - 12y = - 9 + 13 \\ - 4x = 4 \\ x = - 1$

$- 9a - 7 = - 15a + 5 \\ - 9a + 15a = 5 + 7 \\ 6a = 12 \\ a = 2$

$12 - 4x = - 12 + 4x \\ - 4x - 4x = - 12 - 12 \\ - 8x = - 24 \\ x = 3$

$4 + 20y = 6 + 18y \\ 20y - 18y = 6 - 4 \\ 2y = 2 \\ y = 1$

$7 - 2x = 3x - 3 \\ - 2x - 3x = - 3 - 7 \\ - 5x = - 10 \\ x = 2$
