Answer 1

2) г

$4(x - 8) = - 3(x + 2) \\ 4x - 32 = - 3x - 6 \\ 4x + 3x = - 6 + 32$

3)

1) Б

$3(2 - x) = - 2(x - 2) \\ 6 - 3x = - 2x + 4 \\ - 3x + 2x = 4 - 6 \\ - x = - 2 \\ x = 2$

2) Г

$9(x - 1) = 15 + 5x \\ 9x - 9 = 15 + 5x \\ 9x - 5x = 15 + 9 \\ 4x = 24 \\ x = 24 \div 4 \\ x = 6$

3) А

$5x + 1 = 2(4 - x) \\ 5x + 1 = 8 - 2x \\ 5x + 2x = 8 - 1 \\ 7x = 7 \\ x = 7 \div 7 \\ x = 1$

4) Д

$x - 7 = 3(x + 1) \\ x - 7 = 3x + 3 \\ x - 3x = 3 + 7 \\ - 2x = 10 \\ 2x = - 10 \\ x = - 10 \div 2 \\ x = - 5$
