Solving Absolute Value Equations
Since there are 2 sides to zero, every absolute value equation should have 2 solutions.
To solve, set the expression inside the absolute value to the positive and negative

Multiple Select
Which 2 equations would be used to solve |3x - 1| = 10? Check all that apply.
3x - 1 = 10
-3x + 1 = 10
3x -1 = - 10
3x+1 = 10
3x +1 = - 10
