Harry is paid 30x + ( 15x * number of additional hours )
James is paid 40x + ( 2x * number of additional hours )

James worked a total of 41 hours hence he was paid 40x + ( 2x * 1 hour ) = 40x + 2x = 42x
Harry and James were paid the same amount last week
Let Harry's additional hours = y

James payment = Harry's payment
42x = 30x + 1.5xy
42x - 30x = 1.5xy
$$\frac{12x}{1.5x}=y$$
$$y=8$$

Harry worked for the first 30 hours and an additional 8 hours = 30 + 8 = 38 hours

Last week, James worked a total of 41 hours, and thus he earned 40x + 2x = 42x dollars. We can let h = the total number of hours Harry worked last week and create the equation:

30x + 1.5x(h - 30) = 42x

30x + 1.5xh - 45x = 42x

1.5xh - 15x = 42x

1.5xh = 57x

1.5h = 57

h = 57/1.5 = 38
