25x+32y-57x=0
Subtract 57x from both sides.
-32x+32y=0
Combine 25x and -57x to get -32x.
-32x=-32y
Subtract 32y from both sides. Anything subtracted from zero gives its negation.
x=y
Cancel out -32 on both sides.
32y=57x-25x
Subtract 25x from both sides.
32y=32x
Combine 57x and -25x to get 32x.
y=x
Cancel out 32 on both sides.
