Since absolute value represents distance from zero, and on a number line we can move in two different directions, you will usually have two solutions to an absolute value equation. First, always isolate the absolute value expression. From there, you will split it into two equations to solve: one where you make the constant on the right side of the equals sign positive, and a second where you make the constant on the right side negative. Solve each of those separately. Check your work by substituting each x-value into the original absolute value equation.
