xx+x\left(x-3\right)\left(-1\right)=4-x
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}+x\left(x-3\right)\left(-1\right)=4-x
Multiply x and x to get x^{2}.
x^{2}+\left(x^{2}-3x\right)\left(-1\right)=4-x
Use the distributive property to multiply x by x-3.
x^{2}-x^{2}+3x=4-x
Use the distributive property to multiply x^{2}-3x by -1.
3x=4-x
Combine x^{2} and -x^{2} to get 0.
3x+x=4
Add x to both sides.
4x=4
Combine 3x and x to get 4x.
x=\frac{4}{4}
Divide both sides by 4.
x=1
Divide 4 by 4 to get 1.
