4x+20+y=1.5
Combine 3x and x to get 4x.
4x+y=1.5-20
Subtract 20 from both sides.
4x+y=-18.5
Subtract 20 from 1.5 to get -18.5.
4x=-18.5-y
Subtract y from both sides.
4x=-y-18.5
The equation is in standard form.
\frac{4x}{4}=\frac{-y-18.5}{4}
Divide both sides by 4.
x=\frac{-y-18.5}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{y}{4}-\frac{37}{8}
Divide -18.5-y by 4.
4x+20+y=1.5
Combine 3x and x to get 4x.
20+y=1.5-4x
Subtract 4x from both sides.
y=1.5-4x-20
Subtract 20 from both sides.
y=-18.5-4x
Subtract 20 from 1.5 to get -18.5.
