7x+9-9x=22
Subtract 9x from both sides.
-2x+9=22
Combine 7x and -9x to get -2x.
-2x=22-9
Subtract 9 from both sides.
-2x=13
Subtract 9 from 22 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.
