Answer:
4(7-3x)
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.
