3xx=3x\times 2x+2y\times 2x
Multiply both sides of the equation by 2x.
3x^{2}=3x\times 2x+2y\times 2x
Multiply x and x to get x^{2}.
3x^{2}=3x^{2}\times 2+2y\times 2x
Multiply x and x to get x^{2}.
3x^{2}=6x^{2}+2y\times 2x
Multiply 3 and 2 to get 6.
3x^{2}=6x^{2}+4yx
Multiply 2 and 2 to get 4.
6x^{2}+4yx=3x^{2}
Swap sides so that all variable terms are on the left hand side.
4yx=3x^{2}-6x^{2}
Subtract 6x^{2} from both sides.
4yx=-3x^{2}
Combine 3x^{2} and -6x^{2} to get -3x^{2}.
4xy=-3x^{2}
The equation is in standard form.
\frac{4xy}{4x}=-\frac{3x^{2}}{4x}
Divide both sides by 4x.
y=-\frac{3x^{2}}{4x}
Dividing by 4x undoes the multiplication by 4x.
y=-\frac{3x}{4}
Divide -3x^{2} by 4x.
