Answer:
27 if variable is near the fraction,
-1/129 if variable is in the denominator and not numerator
Explanation:
make 2/3 have the same denominator as -1/9
2/3*3/3=6/9
6/9x-1/9x=5/9
5/9x+5 = 20
20-5 = 15
5/9x = 15
15/(5/9x) -> x= -1/129
if you mean the whole equation has the variable x and no the denominator then it is equal to 27
