7x-1=20x
Multiply both sides of the equation by 4.
7x-1-20x=0
Subtract 20x from both sides.
-13x-1=0
Combine 7x and -20x to get -13x.
-13x=1
Add 1 to both sides. Anything plus zero gives itself.
x=\frac{1}{-13}
Divide both sides by -13.
x=-\frac{1}{13}
Fraction \frac{1}{-13} can be rewritten as -\frac{1}{13} by extracting the negative sign.
