One number is 7 more than another. the difference between their squares is 161. what are the numbers?

Let's say the numbers are "a" and "b"

now, we know one of them is 7 more than the other, so hmmm let's say "b" is 7 more than "a", so b = a + 7

the difference of their squares is 161, alrite



and surey you know how much that is

now, what's "b"? well, b = a + 7
