When solving Absolute Value Equations, we follow these 4 steps.

Put them in order.

• Create 2 equations, one that is positive and one t
• Solve for x
• Check your answer for extraneous solutions
• Isolate the absolute value on one side of the equa

We always check our solutions becasue there might be ____________________ solutions.

• funny

• correct

• extraneous
