To solve absolute value equations, find x values that make the expression inside the absolute value positive or negative the constant. To graph absolute value functions, plot two lines for the positive and negative cases that meet at the expression's zero.
To solve inequalities with absolute values, use a number line to see how far the absolute value is from zero. Split into two cases: when it is positive or negative. Solve each case with algebra. The answer is both cases together, in intervals or words. Created by Sal Khan and CK-12 Foundation.

Equations with Two Absolute Values For any algebraic expressions, u and v, \(\begin{array} {ll} {\text{if}} &{\quad |u|=|v|} \\ {\text{then}} &{\quad u=−v \text{ or } u=v} \\ \end{array}\)
1 lis 2021 · Howto: Solve an Absolute Value Equation. Isolate the absolute value expression |u| | u | on one side of the equal sign, producing an equation of the form |u| = c | u | = c. If c > 0 c > 0, write and solve two equations: u = c u = c and u = −c u = − c. If c = 0 c = 0, solve the single equation: u = 0 u = 0.
