Two angles are complementary The sum of the measure of the first angle and 1/4 the second angle is 82.5. Find the measure of the angles.

I think that the first equation will look like this: x+y=90, but I am stuck on the set up of the second one.

x + (1/4)y = 82.5

multiply by 4

4x + y = 330

now subtract the first from the second

4x + y = 330

x + y = 90

------------

3x = 240

x = 80

so one is 80 degrees, the other 10 degrees.
