3 hours
You can turn this into an equation:
F = 26 + 31t
Where F is the money Ralph earned, and t is the number of hours he worked.
Plugging in the 119 for F, we get
119 = 26 + 31t
93 = 31t
3 = t
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
