3+x\left(-10\right)=10x+x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
3+x\left(-10\right)=11x
Combine 10x and x to get 11x.
3+x\left(-10\right)-11x=0
Subtract 11x from both sides.
3-21x=0
Combine x\left(-10\right) and -11x to get -21x.
-21x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{-21}
Divide both sides by -21.
x=\frac{1}{7}
Reduce the fraction \frac{-3}{-21} to lowest terms by extracting and canceling out -3.
