Solving absolute value equations and inequalities (Algebra 1, Linear inequalitites) – Mathplanet

 

how to solve absolute value problems

The General Steps to solve an absolute value equation are: Rewrite the absolute value equation as two separate equations, one positive and the other negative; Solve each equation separately; After solving, substitute your answers back into original equation to verify that you solutions are valid; Write out the final solution or graph it as needed. Step 1: Isolate the absolute value expression. Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation. Step 3: Solve for the unknown in both equations. Step 4: Check your answer analytically or graphically. And represents the distance between a and 0 on a number line. An absolute value equation is an equation that contains an absolute value expression. Has two solutions x = a and x = -a because both numbers are at the distance a from 0. You begin by making it into two separate equations and then solving them separately.
