Start with the given equation

Break up the absolute value (remember, if you have , then or )

or Set the expression equal to the original value 10 and it's opposite -10

Now lets focus on the first equation

Add 8 to both sides

Combine like terms on the right side

Divide both sides by 6 to isolate x

Reduce

Now lets focus on the second equation

Add 8 to both sides

Combine like terms on the right side

Divide both sides by 6 to isolate x

Divide

So the solutions to are:

and

Notice if we graph and (just set each side equal to y and graph), we get

Graph of (red) and (green)

and we can see the two graphs intersect at and . So this verifies our answer.
