The graph of the equations was plotted using geogebra graphing and attached.
Let x represent the hours weightlifting and y represent the hours doing cardio exercises.
Since he spend a maximum of 20 hours, hence: 
x + y ≤ 20   (1) 
Also, he spends at least 8 of those hours weightlifting, hence:
x ≥ 8          (2) 
He wants to spend no more than 15 hours doing cardio exercises, this is:
y ≤ 15      (3)
