We can write this as an equation:

800 + 20x = 600 + 30x
where x is the number of weeks.

To solve, we subtract 20x from both sides and subtract 600 from both sides:

800 - 600 = 30x - 20x \\ 200 = 10x
Then, we simplify by dividing both sides by 10:

(200)/(10) = (10)/(10) x \\ 20 = x
Thomas and Ken have to work 20 weeks for their earnings to be the same.
