\left(x+6\right)\left(9x-7\right)=\left(3x+5\right)\left(3x-4\right)
Variable x cannot be equal to any of the values -6,-\frac{5}{3} since division by zero is not defined. Multiply both sides of the equation by \left(x+6\right)\left(3x+5\right), the least common multiple of 3x+5,x+6.
9x^{2}+47x-42=\left(3x+5\right)\left(3x-4\right)
Use the distributive property to multiply x+6 by 9x-7 and combine like terms.
9x^{2}+47x-42=9x^{2}+3x-20
Use the distributive property to multiply 3x+5 by 3x-4 and combine like terms.
9x^{2}+47x-42-9x^{2}=3x-20
Subtract 9x^{2} from both sides.
47x-42=3x-20
Combine 9x^{2} and -9x^{2} to get 0.
47x-42-3x=-20
Subtract 3x from both sides.
44x-42=-20
Combine 47x and -3x to get 44x.
44x=-20+42
Add 42 to both sides.
44x=22
Add -20 and 42 to get 22.
x=\frac{22}{44}
Divide both sides by 44.
x=\frac{1}{2}
Reduce the fraction \frac{22}{44} to lowest terms by extracting and canceling out 22.
