Answer 3

Let's solve the equations step by step:

1. 32x = -8

To solve for x, we need to isolate it on one side of the equation. Divide both sides of the equation by 32:

(32x) / 32 = (-8) / 32

x = -8 / 32

Simplifying further, we get:

x = -1 / 4

So the solution to the equation is x = -1/4.

b) 15x + 3 = 4

Subtract 3 from both sides of the equation:

15x + 3 - 3 = 4 - 3

15x = 1

Divide both sides of the equation by 15:

(15x) / 15 = 1 / 15

x = 1 / 15

Therefore, the solution to the equation is x = 1/15.

4. 9x - 2 = 4x - 22

Subtract 4x from both sides of the equation and add 2 to both sides:

9x - 4x = -22 + 2

5x = -20

Divide both sides of the equation by 5:

(5x) / 5 = (-20) / 5

x = -4

Hence, the solution to the equation is x = -4.
