2A+2B=y
Swap sides so that all variable terms are on the left hand side.
2A=y-2B
Subtract 2B from both sides.
\frac{2A}{2}=\frac{y-2B}{2}
Divide both sides by 2.
A=\frac{y-2B}{2}
Dividing by 2 undoes the multiplication by 2.
A=\frac{y}{2}-B
Divide y-2B by 2.
2A+2B=y
Swap sides so that all variable terms are on the left hand side.
2B=y-2A
Subtract 2A from both sides.
\frac{2B}{2}=\frac{y-2A}{2}
Divide both sides by 2.
B=\frac{y-2A}{2}
Dividing by 2 undoes the multiplication by 2.
B=\frac{y}{2}-A
Divide y-2A by 2.
