X + y = 20 ---> x = 20 - y
2.5x + 3.7y = (3.5)(20) = 70
--> 2.5(20-y) + 3.7y = 70
--> 50 -2.5y +3.7y = 70
--> 1.2y = 20
---> y = 16.66
Answer: 16.66 gallons
Supplementary means they add up to 180
angle 1 = x
angle 2 = x + 166
so x + x + 166 = 180
2x = 14
x = 7
so angle 1 = 7 angle 2 = x + 166 = 173
