Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

To begin with, let's convert this problem into an equation as displayed below:

Let certain number = x

59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7

59 / 7 - ( x + 8 / 7 ) = 19 / 7

59 / 7 - x - 8 / 7 = 19 / 7

- x = 19 / 7 - 59 / 7 + 8 / 7

- x = - 32 / 7

x = 32 / 7

ANSWER:

Therefore, the certain number is 32 / 7.
