You can put this solution on YOUR website!
x, capacity of the CD
y, capacity of one thumb drive

system%284y%2Bx=9%2C5y-x=9%29
Reading carefully and clear thinking are important in forming these equations.

The system is perfectly ready for elimination of x, using adding corresponding members.
9y=18
highlight%28y=2%29------One thumb drive is 2 gigabytes.
