John and jovanti together have 45 marbles both of them lost 5 marbles each and the product of the number of marbles they now have is 124 fibd out how many marbles they had to start with

If John has x marbles, Jivanti will have 45-x marbles.

If both of them lost 5 marbles each, John will have x-5 and Jivanti will have 45-x-5 ie 40-x

Product of the number of marbles left is 124

(x-5) (40-x) = 124

x^2-45x+324=0

x^2-36x-9x+324=0

(x-36) (x-9) = 0

x=36 or 9

The number of marbles with them is 36 and 9
