To solve the equation 120 = -30 - 5x:

Add 30 to both sides to isolate the variable term: 120 + 30 = -30 + 30 - 5x
Simplify: 150 = -5x
Divide both sides by -5 to solve for x: 150 / -5 = -5x / -5
Simplify: -30 = x

So, the solution to the equation is x = -30.

To solve the equation 120 = -30 - 5x, you first need to isolate the variable x. Begin by adding 30 to both sides of the equation to move the constant term to the other side of the equation:

120 + 30 = -30 + 30 - 5x

This simplifies to:

150 = -5x

Now, divide both sides of the equation by -5 to solve for x:

150 / -5 = -5x / -5

This results in:

-30 = x

So, the solution to the equation 120 = -30 - 5x is x = -30.
