2+3x\times 4y=12x^{2}\times 2x
Multiply both sides of the equation by 2x, the least common multiple of x,2.
2+12xy=12x^{2}\times 2x
Multiply 3 and 4 to get 12.
2+12xy=12x^{3}\times 2
To multiply powers of the same base, add their exponents. Add 2 and 1 to get 3.
2+12xy=24x^{3}
Multiply 12 and 2 to get 24.
12xy=24x^{3}-2
Subtract 2 from both sides.
\frac{12xy}{12x}=\frac{24x^{3}-2}{12x}
Divide both sides by 12x.
y=\frac{24x^{3}-2}{12x}
Dividing by 12x undoes the multiplication by 12x.
y=2x^{2}-\frac{1}{6x}
Divide 24x^{3}-2 by 12x.
