The sum of 2ab2 and (-5ab2) is the same as the sum of (-6ab2) and ____

Answer 1

The answer is 3ab2; since the sum of 2ab2 and (-5ab2) is -3ab2, we need to add a number to equal (-3ab2).

Answer 2

Answer:

3ab^2

Step-by-step explanation:

$2ab^{2} + (-5ab^{2}) = 2ab^{2}-5ab^{2} = -3ab^{2}$

Now,

$-6ab^{2}+x = -3ab^{2}$

$x = -3ab^{2}+6ab^{2}$

$x = 3ab^{2}$
