# 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 #.
