**Reiny**, Thursday, December 16, 2010 at 9:53pmlet the number of white marbles in the first jar be x

then the number of red marbles in the first jar is 7x

total in jar 1 is 8x

let the number of white marbles in jar 2 be y

then the number of red marbles in jar 2 is 9y

total in jar 2 is 10y

but 8x = 10y

x = (5/4)y

also 8x + 10y = 90

8(5/4)y + 10y = 90

10y + 10y = 90

y = 4.5

but both x and y must be whole numbers,

Your question is flawed.
