50x+1000=2000-75y
Subtract 75y from both sides.
50x=2000-75y-1000
Subtract 1000 from both sides.
50x=1000-75y
Subtract 1000 from 2000 to get 1000.
\frac{50x}{50}=\frac{1000-75y}{50}
Divide both sides by 50.
x=\frac{1000-75y}{50}
Dividing by 50 undoes the multiplication by 50.
x=-\frac{3y}{2}+20
Divide 1000-75y by 50.
75y+1000=2000-50x
Subtract 50x from both sides.
75y=2000-50x-1000
Subtract 1000 from both sides.
75y=1000-50x
Subtract 1000 from 2000 to get 1000.
\frac{75y}{75}=\frac{1000-50x}{75}
Divide both sides by 75.
y=\frac{1000-50x}{75}
Dividing by 75 undoes the multiplication by 75.
y=\frac{40-2x}{3}
Divide 1000-50x by 75.
