3y\times 2=\frac{2}{3}\times 12x
Multiply both sides of the equation by 12y, the least common multiple of 4,3,y.
6y=\frac{2}{3}\times 12x
Multiply 3 and 2 to get 6.
6y=8x
Multiply \frac{2}{3} and 12 to get 8.
8x=6y
Swap sides so that all variable terms are on the left hand side.
\frac{8x}{8}=\frac{6y}{8}
Divide both sides by 8.
x=\frac{6y}{8}
Dividing by 8 undoes the multiplication by 8.
x=\frac{3y}{4}
Divide 6y by 8.
3y\times 2=\frac{2}{3}\times 12x
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 12y, the least common multiple of 4,3,y.
6y=\frac{2}{3}\times 12x
Multiply 3 and 2 to get 6.
6y=8x
Multiply \frac{2}{3} and 12 to get 8.
\frac{6y}{6}=\frac{8x}{6}
Divide both sides by 6.
y=\frac{8x}{6}
Dividing by 6 undoes the multiplication by 6.
y=\frac{4x}{3}
Divide 8x by 6.
y=\frac{4x}{3}\text{, }y\neq 0
Variable y cannot be equal to 0.
