-10x=4-2y
Subtract 2y from both sides.
\frac{-10x}{-10}=\frac{4-2y}{-10}
Divide both sides by -10.
x=\frac{4-2y}{-10}
Dividing by -10 undoes the multiplication by -10.
x=\frac{y-2}{5}
Divide 4-2y by -10.
2y=4+10x
Add 10x to both sides.
2y=10x+4
The equation is in standard form.
\frac{2y}{2}=\frac{10x+4}{2}
Divide both sides by 2.
y=\frac{10x+4}{2}
Dividing by 2 undoes the multiplication by 2.
y=5x+2
Divide 4+10x by 2.
