42x=30x+1.5x(H-30)
==> 42=30+1.5(H-30)
==> H-30 = 24/3=8 ==> H = 38

James worked for 41 hours hence he earned 40*x+1*2x=42x dollars;

We know that Harry also earned the same 42x dollars, out of which he earned 30x dollars for the first 30 hours plus 12x additional dollars. Since for each additional hour he gets 1.5x dollars then he worked for 12x/1.5x=8 additional hours, so Harry worked for total of 30+8=38 hours.

Hope it's clear.

Hi Bunuel,
could you please tell me why my approach is incorrect.
Total hours worked by Harry is H
Number of additional hours = H-30
Total earned by James is 42 as you calculated

30x+(H-30)1.5x = 42x
(H-30)1.5x=12x= 1.5x -45=12= x=67/1.5==44 hours

30x+(H-30)1.5x = 42x
(H-30)1.5x=12x= 1.5x -45=12= x=67/1.5==44 hours

Equation is correct, math is not: 30x+(H-30)1.5x=42x--> (H-30)1.5=12 --> H-30=8 --> H=38.

Hope it's clear.

James worked a total of 41 hours, hence James earned amount = 40x + 2x = 42x

Harry and James were paid the same amount last week.Let y be the number of additional hours that Harry has worked over and above the 30 hrs

therefore 42x = 30x (amount Harry earned for the first 30 hours) + 1.5xy

12x = 1.5xy

Hence, y = 8

Since y is the incremental number of hours that Harry has worked,

Harry has worked a total of 30 + 8 = 38 hours last week

I used simple substitution.
Let's assume both of them are paid 10 \$ per hour.
Since Harry and James are paid the same amount then :
10*30+1.5*10*t (time)= 10*40+20 (we know that James worked for total 41 hours)
300+15t=420
t=8 hours ==> Harry worked for 30+8 = 38 hours
