Your question is a bit unclear, but I will try to answer it anyway.
The expression 3x + 2(x - 1) - 4 simplified is:
3x + 2(x - 1) - 4
= 3x + 2x - 2 - 4
= 5x - 6
I cannot tell what the answers are but I am guessing they are these?:
A) 3x + 2x - 2 - 4
B) 5x - 6
C) 3(x - 4)
D) 3(x + 2) - 6
E) 6(x - 1)
Answer A is one, and so is answer B. If I read your question accurately.
I hope I helped!

Answer:
Each would equal 10 lbs.
Step-by-step explanation:
60 pounds all together is the weight of 6 boxes, so if you divide 60 by 6, you'll get 10 lbs for each box.
12 +4m = 24
4m = 12
m = 12/4
m = 3 so choice C. is right sure
