1

Understand the problem

x−(3x+4y)=? x-(3x+4y)=\text{?}

2

Step-by-step solution

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

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

x−3x−4y= x-3x-4y=

Now we group the X factors:

x−3x=−2x x-3x=-2x

We obtain:

−2x−4y -2x-4y

3

Final Answer

−2x−4y -2x-4y
