Answer 1

Hi, I'd be glad to help you. 

x = 12 

Hope this helps. 
Have a great day! 

PS: I calculated your steps and got the answer didn't think you wanted to much information lol.

Answer 2

the answer would be D. first you will have to combine like terms. so 3x + x will be 4x = 2x + 24. then subtract 2x from both sides and that will get you to have 2x = 24. after that divide by 2 on both sides. x will be equal to 12
