5+1x-4x=0
Subtract 4x from both sides.
5-3x=0
Combine 1x and -4x to get -3x.
-3x=-5
Subtract 5 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-5}{-3}
Divide both sides by -3.
x=\frac{5}{3}
Fraction \frac{-5}{-3} can be simplified to \frac{5}{3} by removing the negative sign from both the numerator and the denominator.
