X = 2. Here’s a link; https://www.tiger-algebra.com/drill/(7x-5)_5=14/
Subtract the x on the left from the 2x on the right side
a is the answer as the only change is the gradient being halved,
b would be if it was -1/2 and c would be1/2 x+1/2
Common factor is such a term which can be taken out common from each term of the expression.
If you observe the given expression, 2x can be taken out common leaving the expression which cannot be factored any further.
14x² - 12x
= 2x (7x - 6)
So 2x is the common factor. The answer to this question is option C
