Answer:Let's call the two numbers x and y.
From the problem, we know that:
x + y = 67 (equation 1)
and
x - y = 13 (equation 2)
To solve for x and y, we can use the method of elimination. We can add equations 1 and 2 to eliminate y:
(x + y) + (x - y) = 67 + 13
Simplifying this equation, we get:
2x = 80
Dividing both sides by 2, we get:
x = 40
Now we can use equation 1 to solve for y:
x + y = 67
40 + y = 67
Subtracting 40 from both sides, we get:
y = 27
Therefore, the two numbers are 40 and 27.
