7x−(4b+3x)=? 7x-(4b+3x)=\text{?} 7x−(4b+3x)=?
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= 7x−4b−3x=
Now we group the X factors:
7x−3x=4x 7x-3x=4x 7x−3x=4x
Now we obtain:
4x−4b 4x-4b 4x−4b
