2\left(w-2\right)-9=9w+9
Multiply both sides of the equation by 9.
2w-4-9=9w+9
Use the distributive property to multiply 2 by w-2.
2w-13=9w+9
Subtract 9 from -4 to get -13.
2w-13-9w=9
Subtract 9w from both sides.
-7w-13=9
Combine 2w and -9w to get -7w.
-7w=9+13
Add 13 to both sides.
-7w=22
Add 9 and 13 to get 22.
w=\frac{22}{-7}
Divide both sides by -7.
w=-\frac{22}{7}
Fraction \frac{22}{-7} can be rewritten as -\frac{22}{7} by extracting the negative sign.
