When a is divided by b the quotient is 7 and the remainder is 8. (a-b=74).Find the numbers
What have you tried so far and where are you stuck?
You mention Dividend = Divisor x Quotient + Remainder, which allows you to write

> a is divided by b the quotient is 7 and the remainder is 8

as  a = 7b + 8. Then you have a system of equations with a and b, which you can solve for.
