Separate 846 into 3 parts so that the second part is twice the first part and the third part is triple the second part.
Which of the following equations could be used to solve the problem?
846 = x + 2x + 3x
846 = x + 2x + 6x
846 ÷ 3 = x + 2x + 6x

Well let the first part be x. Then the second part has to be 2x. Then, the third part has to be 3(2x)=6x. Thus, the second equation could be used.
