x-y=55
Swap sides so that all variable terms are on the left hand side.
x=55+y
Add y to both sides.
x-y=55
Swap sides so that all variable terms are on the left hand side.
-y=55-x
Subtract x from both sides.
\frac{-y}{-1}=\frac{55-x}{-1}
Divide both sides by -1.
y=\frac{55-x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=x-55
Divide 55-x by -1.
