You can put this solution on YOUR website!
h = number of Harvard library sites
c = number of Cornell library sites
.
h + c = 119
.
h = 2c + 2
.
substitute
.
2c+2 +c = 119
.
3c = 117
.
c = 39
.
h = 2*39 + 2
h = 80
.
check the total
39 + 80 = 119
correct.
.
Answer: Harvard has 80, and Cornell has 39.
.
Done.
