4-x-2x=0
Subtract 2x from both sides.
4-3x=0
Combine -x and -2x to get -3x.
-3x=-4
Subtract 4 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-4}{-3}
Divide both sides by -3.
x=\frac{4}{3}
Fraction \frac{-4}{-3} can be simplified to \frac{4}{3} by removing the negative sign from both the numerator and the denominator.
