\left(x+4\right)\left(2x+3\right)\times 2+\left(x+4\right)\left(2x-3\right)=\left(2x+3\right)\left(3x+5\right)
Variable x cannot be equal to any of the values -4,-\frac{3}{2} since division by zero is not defined. Multiply both sides of the equation by \left(x+4\right)\left(2x+3\right), the least common multiple of 2x+3,x+4.
\left(2x^{2}+11x+12\right)\times 2+\left(x+4\right)\left(2x-3\right)=\left(2x+3\right)\left(3x+5\right)
Use the distributive property to multiply x+4 by 2x+3 and combine like terms.
4x^{2}+22x+24+\left(x+4\right)\left(2x-3\right)=\left(2x+3\right)\left(3x+5\right)
Use the distributive property to multiply 2x^{2}+11x+12 by 2.
4x^{2}+22x+24+2x^{2}+5x-12=\left(2x+3\right)\left(3x+5\right)
Use the distributive property to multiply x+4 by 2x-3 and combine like terms.
6x^{2}+22x+24+5x-12=\left(2x+3\right)\left(3x+5\right)
Combine 4x^{2} and 2x^{2} to get 6x^{2}.
6x^{2}+27x+24-12=\left(2x+3\right)\left(3x+5\right)
Combine 22x and 5x to get 27x.
6x^{2}+27x+12=\left(2x+3\right)\left(3x+5\right)
Subtract 12 from 24 to get 12.
6x^{2}+27x+12=6x^{2}+19x+15
Use the distributive property to multiply 2x+3 by 3x+5 and combine like terms.
6x^{2}+27x+12-6x^{2}=19x+15
Subtract 6x^{2} from both sides.
27x+12=19x+15
Combine 6x^{2} and -6x^{2} to get 0.
27x+12-19x=15
Subtract 19x from both sides.
8x+12=15
Combine 27x and -19x to get 8x.
8x=15-12
Subtract 12 from both sides.
8x=3
Subtract 12 from 15 to get 3.
x=\frac{3}{8}
Divide both sides by 8.
