Answer:
2(2x + 1)
Explanation:
Combine like terms and 3x and x are like terms
3x is just:
x + x + x and you add one more x so its
x + x + x + x
since there are 4, it is 4x.
2 is a number without any modifiers so it stays alone since it is the only one like itself.
4x +2
both number can be divided by 2 so divide by 2 and put it on the outside of parenthesizes and divide both number by 2.
2(2x + 1)
then your done and it is simplified.
