x+2y=1.3
Swap sides so that all variable terms are on the left hand side.
x=1.3-2y
Subtract 2y from both sides.
x+2y=1.3
Swap sides so that all variable terms are on the left hand side.
2y=1.3-x
Subtract x from both sides.
\frac{2y}{2}=\frac{1.3-x}{2}
Divide both sides by 2.
y=\frac{1.3-x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{x}{2}+\frac{13}{20}
Divide 1.3-x by 2.
