Question 79987: One number is 12 more than another. The sum of the smaller number and twice the larger number is 39. Find the larger number. Answer by sofiyacherni(99) (Show Source):
You can put this solution on YOUR website! say we call small number x
then the large number would be x+12
""The sum of the smaller number and twice the larger number is 39"" which translates into
x+2(x+12)=39
x+2x+24=39
3x+24=39
3x=15
x=5
but x was the smaller number so to find the larger number we just have to add 12
5+12=17
17 is the larger number
