4x+5=20x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4x.
4x+5-20x=0
Subtract 20x from both sides.
-16x+5=0
Combine 4x and -20x to get -16x.
-16x=-5
Subtract 5 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-5}{-16}
Divide both sides by -16.
x=\frac{5}{16}
Fraction \frac{-5}{-16} can be simplified to \frac{5}{16} by removing the negative sign from both the numerator and the denominator.
