3x+15y-200x=0
Subtract 200x from both sides.
-197x+15y=0
Combine 3x and -200x to get -197x.
-197x=-15y
Subtract 15y from both sides. Anything subtracted from zero gives its negation.
\frac{-197x}{-197}=-\frac{15y}{-197}
Divide both sides by -197.
x=-\frac{15y}{-197}
Dividing by -197 undoes the multiplication by -197.
x=\frac{15y}{197}
Divide -15y by -197.
15y=200x-3x
Subtract 3x from both sides.
15y=197x
Combine 200x and -3x to get 197x.
\frac{15y}{15}=\frac{197x}{15}
Divide both sides by 15.
y=\frac{197x}{15}
Dividing by 15 undoes the multiplication by 15.
