Personally I prefer non of these definition. But for the sake of a multiple choice question, I can see that the last one to be the "closest".
Answer: x = 8
Step-by-step explanation:
8(3-2x) + 4(3x - 2) = -16
expanding the equation , we have
24 - 16x +12x - 8 = -16
16 - 4x = -16
collecting the like terms
4x = 32
x = 32/4
x = 8
2,240 divided by 28= 80. 80 times 32= 2,560. 2,560+2,240=4800. Figure out the rest alone xD
