There are two people in this problem and both of them get time for playing if they complete the homeworks in their allotted time.
Taking the first instance of Jonathan
For every 5 hours of doing homework, the number of hours Jonathan
gets for playing video games = 3 hours
Then
For every 1 hour of doing homework, the number of hours Jonathan
gets for playing video games = (3/5) * 1 hours
= 3/5 hours
= 0.6 hours
= (0.6 * 60) minutes
= 36 minutes
Taking the second instance of Lucas
For every 1 hour of doing homework, the number of minutes Lucas
gets for playing video games = 30 minutes
Then we can easily say that if both Jonathan and Lucas spend the same amount of time doing homework, then Jonathan gets more playing time than Lucas.
I do believe you're asking in the wrong place.....

First, subtract k from both sides. That means c - k is in the left side and 3x is on the right. Then, divide by 3 on both sides. So, the answer is x = (c - k) / 3.
