Answer:

Step-by-step explanation:

START: 4x + 10 = - 26 ⇔ 4x = - 36 ⇔ x = - 9

$\frac{1}{2}$ x + 13 = 9 ⇔ $\frac{1}{2}$ x = - 4 ⇔ x = 8

$\frac{3}{4}$ x - 9 = 27 ⇔ $\frac{3}{4}$ x = 36 ⇔ x = 48

9 - 2x = 35 2x = - 35 + 9 ⇔ x = - 13

$\frac{2}{3}$ x + 15 = 17 ⇔ $\frac{2}{3}$ x = 2 ⇔ x = 3

- 5x - 10 = 10 ⇔ 5x = - 20 ⇔ x = - 4

Now is your turn. You can do it!!!
