The first step for solving this equation is to multiply the first two numbers together.
18 + 24x + 32 = 0
Add together 18 and 32.
50 + 24x = 0
Now move the constant to the right side of the equation and change its sign.
24x = -50
Lastly,, divide both sides of the equation by 24.
x =

This means that the correct answer to your question is going to be x =
