The idea is to change the equation in such a way that the "x" remains isolated (alone) on one side of the equation. In this case, first add 1 to both side of the equation. This will eliminate the "-1" on the left. Then, divide both sides by 5. This will eliminate the 5, and leave the "x" alone. Whatever is left on the right is the solution.
