The sum of two numbers is 18 and their difference is 2. What are the numbers?

To solve for the two numbers, let’s denote them as x and y.

We know from the problem statement:

  • The sum of the two numbers: x + y = 18
  • Their difference: x – y = 2

We can solve this system of equations step by step.

1. First, we can express one variable in terms of the other from the second equation. From x – y = 2, we can isolate x:

x = y + 2

2. Now we can substitute this expression for x into the first equation:

(y + 2) + y = 18

3. Combining like terms gives us:

2y + 2 = 18

4. Next, we subtract 2 from both sides:

2y = 16

5. Now, dividing both sides by 2 yields:

y = 8

6. Now that we have y, we can find x using the expression we derived earlier:

x = 8 + 2 = 10

Finally, the two numbers are x = 10 and y = 8.

In conclusion, the two numbers you’re looking for are 10 and 8.
