The absolute value of an equation makes no sense. Do you mean you want the solution to the given absolute value equation?

Going on that assumption:



Multiply both sides by




Consider the positive case:



Solve for the first value of

Consider the negative case:



Solve for the second value of

Substitute each of the solutions back into the original absolute value equation to verify that you don't have any extraneous solutions.
