\left(3x-2\right)\left(x+1\right)=\left(x-1\right)\left(3x+5\right)
Variable x cannot be equal to any of the values \frac{2}{3},1 since division by zero is not defined. Multiply both sides of the equation by \left(x-1\right)\left(3x-2\right), the least common multiple of x-1,3x-2.
3x^{2}+x-2=\left(x-1\right)\left(3x+5\right)
Use the distributive property to multiply 3x-2 by x+1 and combine like terms.
3x^{2}+x-2=3x^{2}+2x-5
Use the distributive property to multiply x-1 by 3x+5 and combine like terms.
3x^{2}+x-2-3x^{2}=2x-5
Subtract 3x^{2} from both sides.
x-2=2x-5
Combine 3x^{2} and -3x^{2} to get 0.
x-2-2x=-5
Subtract 2x from both sides.
-x-2=-5
Combine x and -2x to get -x.
-x=-5+2
Add 2 to both sides.
-x=-3
Add -5 and 2 to get -3.
x=3
Multiply both sides by -1.
