10x=2+y
Add y to both sides.
10x=y+2
The equation is in standard form.
\frac{10x}{10}=\frac{y+2}{10}
Divide both sides by 10.
x=\frac{y+2}{10}
Dividing by 10 undoes the multiplication by 10.
x=\frac{y}{10}+\frac{1}{5}
Divide 2+y by 10.
-y=2-10x
Subtract 10x from both sides.
\frac{-y}{-1}=\frac{2-10x}{-1}
Divide both sides by -1.
y=\frac{2-10x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=10x-2
Divide 2-10x by -1.
