6\times 5=x+2y
Multiply 2 and 3 to get 6.
30=x+2y
Multiply 6 and 5 to get 30.
x+2y=30
Swap sides so that all variable terms are on the left hand side.
x=30-2y
Subtract 2y from both sides.
6\times 5=x+2y
Multiply 2 and 3 to get 6.
30=x+2y
Multiply 6 and 5 to get 30.
x+2y=30
Swap sides so that all variable terms are on the left hand side.
2y=30-x
Subtract x from both sides.
\frac{2y}{2}=\frac{30-x}{2}
Divide both sides by 2.
y=\frac{30-x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{x}{2}+15
Divide 30-x by 2.
