Question 1036719

The sum of the ages of John and Shane before six years was 13 years. The sum of their ages after 8 years will be ________.
Thank you !!!!
<pre>Let John's and Shane's ages, be J, and S, respectively
Then 6 years ago, we had: J + S - 2(6) = 13
J + S - 12 = 13
J + S = 13 + 12
J + S = 25
In 8 years, sum of ages, or J + S + 2(8), or J + S + 16
Since J + S = 25, then J + S + 16 becomes: 25 + 16, or {{{highlight_green(41 )}}}
