Learn to solve and graph absolute value equations, including finding x values and plotting v-shaped graphs for positive and negative cases.

Understand why an absolute value equation can have from 0 to 2 solutions. Solve absolute value equations with different numbers of solutions. Created by Sal Khan.

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 …

This topic covers: - Solving absolute value equations - Graphing absolute value functions - Solving absolute value inequalities

You can't take the absolute value of the individual parts. We follow PEMDAS rules. The absolute value is a special case of parentheses. We do the work inside the parentheses 1st. The …

Now just as promised, we want to solve for the absolute value of x plus 7, so let's divide both sides by 14 to get rid of that coefficient there, or that factor, or whatever you want to call it, the …

When solving absolute value equations, rewrite the equation as two linear equations, then solve each linear equation. Both solutions are solutions to the absolute value equation.

Any value of "x" will still create a positive value on the side with the absolute value. If you choose to solve the inequality, you would do the following steps:

If you take the absolute value of negative 3 and 1/4, you'll get positive 3 and 1/4, which won't work. 3 and 1/4 is greater than 2 and 1/2, so that's true, that works out.
