The measure of an angle is 21° more than twice its supplement. find the measure of each angle

So supplement angles are angles that add up to 180 so

so x=180-y
it's kind of hard to represent the problem but this is my way (which is basically trial and error and math stuff (confusing) and uses luck)
so
x=21+2y
x+y=180
so since the above equations are true then
((180-21)/3)=53= supplement=53

angle=127
supplement=53

trial and error and accient
127=21+2(53)
127=21+106
127=127
