Absolute Value Equations Simplify: Complete each statement with <, =, or >:

Fill in the absolute values so that each expression is true.

Fill in the absolute values so that each expression is true.

Lets look at that last example

Solving these two equations gives

Let’s check to see if this makes sense

Remember, that absolute value means “how far away from zero.” Therefore, means ♣ is exactly 4 units away from 0.

Solve for x

And here is the check

Remember, we can solve for anything

Note When solving an absolute value equation, you need to make sure the absolute value is isolated on the left side of the equation BEFORE you can remove the absolute value symbol!!!
