Question

What should be added to -3a + 7b - 16 to get 4a - 3b + 19.

Answer 1

Answer:

7a - 10b + 35

Step-by-step explanation:

Let the expression to be added be x.

ATQ,

(-3a + 7b - 16) + x = 4a - 3b + 19

⇒ x = 4a - 3b + 19 + 3a - 7b + 16

⇒ x = 7a - 10b + 35

Thus, 7a - 10b + 35 should be added to -3a + 7b - 16 to get 4a - 3b + 19.

Hope it helps...
