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 abs(y) = x , where x is a real number, you may always write y = +- x .
