Your question is not clear. I must guess what you meant. Did you mean "Find the two numbers?"
If so, let the two numbers be m and n. Then mn=60 and m=n-7.
Then (n-7)(n) = 60, or n^2 -7n - 60 = 0. This factors: (n+5)(n-12) = 0
Thus, n = -5 or n = 12.
check: does mn = 60? Does 12*5 = 60? Yes. Is m (which is 5) 7 less than n (which is 12)? Yes.
Note that you could also check to see whether n=-5 and m=n-7=-5-7=-12 is also a solution.
