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