4x+5-8x=20
Subtract 8x from both sides.
-4x+5=20
Combine 4x and -8x to get -4x.
-4x=20-5
Subtract 5 from both sides.
-4x=15
Subtract 5 from 20 to get 15.
x=\frac{15}{-4}
Divide both sides by -4.
x=-\frac{15}{4}
Fraction \frac{15}{-4} can be rewritten as -\frac{15}{4} by extracting the negative sign.
