\left(x+5\right)\left(x-3\right)=\left(x-1\right)\left(x-6\right)
Variable x cannot be equal to any of the values -5,1 since division by zero is not defined. Multiply both sides of the equation by \left(x-1\right)\left(x+5\right), the least common multiple of x-1,x+5.
x^{2}+2x-15=\left(x-1\right)\left(x-6\right)
Use the distributive property to multiply x+5 by x-3 and combine like terms.
x^{2}+2x-15=x^{2}-7x+6
Use the distributive property to multiply x-1 by x-6 and combine like terms.
x^{2}+2x-15-x^{2}=-7x+6
Subtract x^{2} from both sides.
2x-15=-7x+6
Combine x^{2} and -x^{2} to get 0.
2x-15+7x=6
Add 7x to both sides.
9x-15=6
Combine 2x and 7x to get 9x.
9x=6+15
Add 15 to both sides.
9x=21
Add 6 and 15 to get 21.
x=\frac{21}{9}
Divide both sides by 9.
x=\frac{7}{3}
Reduce the fraction \frac{21}{9} to lowest terms by extracting and canceling out 3.
