  3(x ) = 4(x +2)+13
- B.
  
  3(x ) = 4(x ) +13
- C.
  
  3(x +x+1) = 4(x +2) +13
- D.
  
  3(x+1) = 4(x ) +13
Correct Answer
C. 3(x +x+1) = 4(x +2) +13

Explanation
The correct answer is 3(x +x+1) = 4(x +2) +13. This is the correct answer because it follows the given equation 3(x ) = 4(x +2)+13. The equation is balanced on both sides with the same terms and coefficients. The other options do not match the given equation and therefore are not correct.
