\left(2x+3\right)\times 2+\left(x-3\right)\times 2x=\left(x-3\right)\left(2x+3\right)
Variable x cannot be equal to any of the values -\frac{3}{2},3 since division by zero is not defined. Multiply both sides of the equation by \left(x-3\right)\left(2x+3\right), the least common multiple of x-3,2x+3.
4x+6+\left(x-3\right)\times 2x=\left(x-3\right)\left(2x+3\right)
Use the distributive property to multiply 2x+3 by 2.
4x+6+\left(2x-6\right)x=\left(x-3\right)\left(2x+3\right)
Use the distributive property to multiply x-3 by 2.
4x+6+2x^{2}-6x=\left(x-3\right)\left(2x+3\right)
Use the distributive property to multiply 2x-6 by x.
-2x+6+2x^{2}=\left(x-3\right)\left(2x+3\right)
Combine 4x and -6x to get -2x.
-2x+6+2x^{2}=2x^{2}-3x-9
Use the distributive property to multiply x-3 by 2x+3 and combine like terms.
-2x+6+2x^{2}-2x^{2}=-3x-9
Subtract 2x^{2} from both sides.
-2x+6=-3x-9
Combine 2x^{2} and -2x^{2} to get 0.
-2x+6+3x=-9
Add 3x to both sides.
x+6=-9
Combine -2x and 3x to get x.
x=-9-6
Subtract 6 from both sides.
x=-15
Subtract 6 from -9 to get -15.
