Answer:

4(7-3x)

Step-by-step explanation:

You have to find the highest number that can go into both of them.

I found 4

you basically have to divide by 4 on both of the numbers

28 - 12x

÷4    ÷4

7   -   3x

The variable doesn't have another one to pair with.

So it sticks with its self.

Then you basically put the 7-3x in the racks These=()

Then you have to put the 4 in front.
