Complementary Angles math problem?

Question

Two angles are complementary if the sum of the measures of the angles is 90 degrees. If one angle is ten more than 3 times its complement, find the measures of the two angles.

anybody know?

Answer 1

x + y = 90

x = 3y + 10

solve the system

Answer 2

There is an even easier method

x is one angle

x + (3x+10) = 90

4x +10 = 90

4x = 80

x = 20
