62.5+80+x+y=85\times 4
Multiply both sides by 4.
142.5+x+y=85\times 4
Add 62.5 and 80 to get 142.5.
142.5+x+y=340
Multiply 85 and 4 to get 340.
x+y=340-142.5
Subtract 142.5 from both sides.
x+y=197.5
Subtract 142.5 from 340 to get 197.5.
x=197.5-y
Subtract y from both sides.
62.5+80+x+y=85\times 4
Multiply both sides by 4.
142.5+x+y=85\times 4
