Javier = \(j\) hours
Devlin = \(d\) hours
\(Javier\) worked seven hours more than three times the number of hours that \(Devlin\) worked.
\(j = 3d + 7\)
\(j\) & \(d\) are integers.
Possible value of \(j\) can be
if \(d = 1, j = 10\)
\(d = 2, j = 13,\)
\(d = 3, j = 16\)
The possible values can be from this series : \(10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43...\)
