You can put this solution on YOUR website!
System of Equations:
Let the number of pics James has = J
Let the number of pics Kelvin has = K
J%2BK=2100
K%2B300=J
Plug in:
J=300%2BK
%28300%2BK%29%2BK=2100
300%2B2K=2100
2K=1800
K=900
Kelvin has 900 Pics
If you need to know how many James has, you can plug Kelin's number back in:
J=300%2BK
J=300%2B900
J=1200
James has 1200 Pics
