Answer 2

Answer:

34bc + 70

Step-by-step explanation:

Lets take a constant example to get explained better.

Ex. 10-__=4

In this we have to find the value of the dash.

To find the answer we will subtract 4 from 10 which will give 6.

In the similar way we will do as the question says.

-15ac+37bc+70 - _______________ = 15ac-3bc

We will do it as follows:-

-15ac+37bc+70 - 15ac-3bc

(Combine in groups now)

-15ac - 15ac + 37bc - 3bc + 70
