One method for solving absolute value equations is to first isolate the absolute value expression, and then replace the absolute value signs with + - ( ) . Next, you split your equation into two equations to solve- one with + ( ), and the other with - ( ) where you will distribute the negative. Solve each for x. Check your work by plugging each answer in to the original absolute value equation.
