Question 105768
One number is 12 more than another.  The sum of the smaller number and twice the larger number is 39.  Find the larger number.
5
7
17
34

Let x = first number
then x + 12 = larger number

{{{x+2(x+12)=39}}}
Solving, we have:
{{{x+2x+24=39}}}
{{{3x = 15}}}
{{{x=5}}}
{{{x + 12 = 5 + 12 = 17}}}
Therefore, the numbers are 5 and 17, the larger number is 17.

Thank you.
