Question 1024042
Let j and m be the number of tickets John and Mike sold.  Then we can write
j + m = 58  and
j = m + 14
These are the equations we use to solve this.
To do so, we will substitute into the first equation, like this...
m+14 + m = 58
2m + 14 = 58
2m = 44
m = 22 tickets
j = m + 14 = 36 tickets
