xx+5x-1=x\left(x-3\right)
Variable x cannot be equal to any of the values 0,3 since division by zero is not defined. Multiply both sides of the equation by x\left(x-3\right), the least common multiple of x-3,x^{2}-3x.
x^{2}+5x-1=x\left(x-3\right)
Multiply x and x to get x^{2}.
x^{2}+5x-1=x^{2}-3x
Use the distributive property to multiply x by x-3.
x^{2}+5x-1-x^{2}=-3x
Subtract x^{2} from both sides.
5x-1=-3x
Combine x^{2} and -x^{2} to get 0.
5x-1+3x=0
Add 3x to both sides.
8x-1=0
Combine 5x and 3x to get 8x.
8x=1
Add 1 to both sides. Anything plus zero gives itself.
x=\frac{1}{8}
Divide both sides by 8.
