\left(3x+2\right)\left(x+6\right)-\left(x-5\right)=\left(3x+2\right)\left(x+3\right)
Variable x cannot be equal to any of the values -\frac{2}{3},5 since division by zero is not defined. Multiply both sides of the equation by \left(x-5\right)\left(3x+2\right), the least common multiple of x-5,3x+2.
3x^{2}+20x+12-\left(x-5\right)=\left(3x+2\right)\left(x+3\right)
Use the distributive property to multiply 3x+2 by x+6 and combine like terms.
3x^{2}+20x+12-x+5=\left(3x+2\right)\left(x+3\right)
To find the opposite of x-5, find the opposite of each term.
3x^{2}+19x+12+5=\left(3x+2\right)\left(x+3\right)
Combine 20x and -x to get 19x.
3x^{2}+19x+17=\left(3x+2\right)\left(x+3\right)
Add 12 and 5 to get 17.
3x^{2}+19x+17=3x^{2}+11x+6
Use the distributive property to multiply 3x+2 by x+3 and combine like terms.
3x^{2}+19x+17-3x^{2}=11x+6
Subtract 3x^{2} from both sides.
19x+17=11x+6
Combine 3x^{2} and -3x^{2} to get 0.
19x+17-11x=6
Subtract 11x from both sides.
8x+17=6
Combine 19x and -11x to get 8x.
8x=6-17
Subtract 17 from both sides.
8x=-11
Subtract 17 from 6 to get -11.
x=\frac{-11}{8}
Divide both sides by 8.
x=-\frac{11}{8}
Fraction \frac{-11}{8} can be rewritten as -\frac{11}{8} by extracting the negative sign.
