Hey mate here is your answer↓↓↓

Step 1:First add the numbers who have x as variable.

That is, 7x+14x+21x-2=42x-2

Step 2:Then factorize it by taking 2 in common

That is, 2(21x-1)

Hope it helps

Just do 7x + 14x+21x which is 42x

-2 does not have an x meaning it is not a common factor if u will

So your answer is 42x-2


Hope this helps :)
