1. Solving Equations Using Addition or Subtraction
Sign In
To solve the equation, we have to isolate x on one side. Using the Subtraction Property of Equality, we will subtract 4 from both sides of the equation. This will eliminate the addition and isolate x.
To check that this solution is correct, let's substitute x = - 18 into the original equation and simplify.
Since the left-hand side and right-hand side are equal, x = - 18 is the correct solution.
