x=4\times 2y
Multiply both sides of the equation by 12, the least common multiple of 12,3.
x=8y
Multiply 4 and 2 to get 8.
x=4\times 2y
Multiply both sides of the equation by 12, the least common multiple of 12,3.
x=8y
Multiply 4 and 2 to get 8.
8y=x
Swap sides so that all variable terms are on the left hand side.
\frac{8y}{8}=\frac{x}{8}
Divide both sides by 8.
y=\frac{x}{8}
Dividing by 8 undoes the multiplication by 8.
