When I did equation 4 divided by equation 5, x will be divided by x and it's equals to 1. I didn't reflect it in the solution. Just take note of that.
So from the first equation, you can see that we have 3 unknowns:
1. Cost of key chain represented by k
2. Cost of mug represented by m
3. Quantity bought represented by x
