To solve an absolute value problem, you have to isolate the absolute value bars, and then make two equations. Here, I'll show you:

First, I'll subtract 6 from both sides. Some people think you should add six to both sides because they see subtraction, but look at JUST the six. Isn't it actually a positive six? To "undo" a positive six, you subtract six (and I know it's positive because it always takes the sign just to the left...since there isn't a sign just to the left, we assume it's positive)

-6 here, and -6 on this side also

multiply both sides by negative one:
so now both sides are positive instead of negative.

now wouldn't you agree that if the problem was just

that "something" would have to be either 25 or -25?
well that's why
means
either or

if you solve the first one you get:

by solving the second one, we get:

So there are 2 solutions, or
If you don't believe me, try plugging them back in! It's a great way to check your answer! See? I'll plug -5.5 in:

Do 4 times -5.5 to get

Now -22-3 equals -25 so:

and the absolute value of -25 is 25:
which is true, so -5.5 works!!!
