All the given terms have the same variables. Therefore they can be added together.

2ab + (-7ab) + (2/3 ab) + 9ab

2ab - 7ab + 9ab + 2/3ab

(Removing the brackets)

-5ab + 9ab + 2/3 ab

(2 - 7 = -5)

4ab + 2/3 ab

(-5 + 9 = 4)

12/3 ab + 2/3 ab

(Taking the LCM to make them like fractions)

15/3 ab

(Now simplify)

5ab
