Answer 1

Q) (ab - 2a + 3b) + (5a - 3ab + 6b)

A) Just group all like terms together then its just easy addition or subtraction.

= ab - 3ab - 2a + 5a + 3b + 6b

= -2ab +3a + 9b

Hence, your answer is -2ab + 3a + 9b.

Answer 2

Answer:

Step-by-step explanation:

(ab - 2a + 3b) + (5a - 3ab + 6b)

Bringing similar together,

ab - 2a + 3b + 5a - 3ab + 6b (Opening bracket)

(ab - 3ab) + (- 2a + 5a) + (3b + 6b)

On solving, we get,

-2ab + 3a + 9b

Can also be written as 3a + 9b - 2ab

or 3a - 2ab + 9b
