Find the larger of two supplementary angles, Mathematics

The larger of two supplementary angles exceeds the smaller by 180, find them. (Ans:990,810)

Ans:    x + y = 1800

         x - y =  180

       -----------------

           2x  = 198

x = 198 / 2  =  x = 990

x + y = 1800

y = 180 - 99

y = 810
