Answer
Cornell: 39; Harvard: 80
Work Step by Step
We first call the number of Cornell libraries x. Then translate the number of Harvard libraries to the expression 2x + 2. The sum of both is 119, so we write the equation:
x + (2x + 2) = 119
Solve for x:
3x + 2 = 119
3x = 117
x = 39
The nuber of Cornell ibraries is x = 39, and the number of Harvard libraries is 2x + 2 = 2(39) + 2 = 80.
