Solve for x . −20=−5+3x

Answer 1

To solve for x in the equation -20 = -5 + 3x, we need to isolate x on one side of the equation.

First, let's simplify the equation by combining like terms:

-20 = -5 + 3x

Next, let's get rid of the -5 on the right side of the equation by adding 5 to both sides:

-20 + 5 = -5 + 5 + 3x

-15 = 3x

To isolate x, divide both sides of the equation by 3:

-15/3 = 3x/3

-5 = x

Therefore, x = -5.
