x+4y=3-1
Subtract 1 from both sides.
x+4y=2
Subtract 1 from 3 to get 2.
x=2-4y
Subtract 4y from both sides.
x+4y=3-1
Subtract 1 from both sides.
x+4y=2
Subtract 1 from 3 to get 2.
4y=2-x
Subtract x from both sides.
\frac{4y}{4}=\frac{2-x}{4}
Divide both sides by 4.
y=\frac{2-x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{x}{4}+\frac{1}{2}
Divide 2-x by 4.
