(a-1)b-1 when we try to solve it as multiply (a-1) to b then we get
ab-b
then after there is -1
then collect all then see we get
ab-b-1 this is equal to RHS

hope u get it :-)

Hello friend, 
Here's your answer:

(a - 1)b - 1 = ba - b - 1
=> b(a - 1) - 1 = b(a - 1) - 1
Since LHS = RHS, we obtain your 'how' component of the question.

Hope my answer helps you.
