Answer: 4(x + 3y)
Explanation: the common multiple of both 12 and 4 in this case is 4. (4/4 = 1 and 12/4 =3) since x and y aren’t like terms, the number outside the bracket can’t have either variable. that’s why its just 4. then using that common multiple idea, divide 4x/4 to get x and divide 12y/4 to get 3y and place them inside the bracket. (Dont forget the addition sign!)
Hope this helps! :)
