"Two fewer than a number" doubled
2(n-2) = n-38
Two fewer than "a number doubled"
2n-2 = n-38
Thank Yu. Unknowns seem to get me stuck. I have another one.
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?
call the parts a,b,c
a+b+c = 846
b = 2a
c = 3b
substitute in for b and c to get
a+2a+6a = 846
9a = 846
a = 94
To solve this kinda stuff, just take it one step at a a time. First, translate the words into symbols. Then substitute things as needed. After a thousand or so, you'll get the hang of it. :-)
