y=±5

Explanation:

Whenever there is an equation to solve, what is actually being asked is to find out the set of values that satisfy the equation. In this case, we know that y=+5 and y=5 would satisfy the equation. Thus the solution is y=±5.

In general, if you have |y|=x, where x is a real number, you may always write y=±x.
