Three times the complement of an angle less the supplement of an angle is 10. find the supplement.
I've started.
3c-s=10
3(90-x) - 180 - x =10
You should put the supplement in brackets
270 - 3x - (180 - x) = 10;
which will remind you to change the sign of x
270 - 3x - 180 + x = 10
combine like terms
-3x + x + 270 - 180 = 10
-2x + 90 = 10
-2x = 10 - 90
-2x = - 80
x =
x = +40

Check solution in original equation
3(90-40) - (180-40) =
3(50) - 140 = 10; confirms our solution of x = 40
