x+5=2y-3
Swap sides so that all variable terms are on the left hand side.
x=2y-3-5
Subtract 5 from both sides.
x=2y-8
Subtract 5 from -3 to get -8.
2y=x+5+3
Add 3 to both sides.
2y=x+8
Add 5 and 3 to get 8.
\frac{2y}{2}=\frac{x+8}{2}
Divide both sides by 2.
y=\frac{x+8}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{x}{2}+4
Divide x+8 by 2.
