Lisa is thinking about two positive integers. The larger integer is seven less than twice the smaller integer. The larger integer is also three more than the smaller integer.

What is the larger of the two integers that Lisa is thinking about?

~So the problem just throws me off completely cause there is no starting number.Please show me how to do it. Thanks!

let the numbers be L and S
L=2S-7
L=S+3
subtract the second equation from the first..
0=S-10
S=10 which makes L 13
