2x=55+y
Add y to both sides.
2x=y+55
The equation is in standard form.
\frac{2x}{2}=\frac{y+55}{2}
Divide both sides by 2.
x=\frac{y+55}{2}
Dividing by 2 undoes the multiplication by 2.
-y=55-2x
Subtract 2x from both sides.
\frac{-y}{-1}=\frac{55-2x}{-1}
Divide both sides by -1.
y=\frac{55-2x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=2x-55
Divide 55-2x by -1.
