The Answer is 6 Dollars
Well here there are two parts You and your friend spent 15 dollars your friends lunch cost 3 more than yours <span>
6=x is the amount you spent on lunch.

$9 spent by your friend.
You=$6
Friend=$9
Total=$15
To prove the solution is valid, plug 6 in for x.
15=3+2(6)
15=3+12
15=15 thus proving the solution is valid.</span>
