9x+7-11x=20
Subtract 11x from both sides.
-2x+7=20
Combine 9x and -11x to get -2x.
-2x=20-7
Subtract 7 from both sides.
-2x=13
Subtract 7 from 20 to get 13.
x=\frac{13}{-2}
Divide both sides by -2.
x=-\frac{13}{2}
Fraction \frac{13}{-2} can be rewritten as -\frac{13}{2} by extracting the negative sign.
