Understand the problem

7x−(4b+3x)=? 7x-(4b+3x)=\text{?}

2

Step-by-step solution

First, we open the parentheses and change the sign accordingly.

Since there are only positive numbers inside the parentheses, multiplying by minus will give us negative numbers:

7x−4b−3x= 7x-4b-3x=

Now we group the X factors:

7x−3x=4x 7x-3x=4x

Now we obtain:

4x−4b 4x-4b
