Answer 2

$\huge\fbox\pink{A}\huge\fbox\blue{n} \huge\fbox\purple{S}\huge\fbox\green{w} \huge\fbox\red{E}\huge\fbox\orange{r}$

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
