You may want to review solving equations and absolute-value equations first.

Suppose you're given an equation with absolute-value signs in it
to solve. For example, it could look like |4*x*| −
2 ⁄ 3 = 0. The first step is to get the
absolute-value part all by itself on one side. We can do that by
adding 2 ⁄ 3 to both sides. Now we have
|4*x*| = 2 ⁄ 3. This means
that *either* 4*x* =
2 ⁄ 3 *or* 4*x* =
−2 ⁄ 3. So we need to solve both of
these equations. Their solutions are 1 ⁄ 6 and
−1 ⁄ 6. That means that *x* is
either 1 ⁄ 6 or
−1 ⁄ 6, so those are our two answers. We
can write this as “{1 ⁄ 6,
−1 ⁄ 6}”. On this website, I've
written the ‘{’ and ‘}’ signs for you,

There might not be any absolute value sign in some problems. Then you solve them just like you learned how to solve equations before. If it's an identity or a contradiction, just say so.
