Answer:

  • x = 40
  • y = 22

Explanation:

We know that:

  • x - y = 18
  • x + y = 62

Work:

  • x - y = 18

x + y = 62

  • => (x + x) + (y - y) = (18 + 62)
  • => 2x + 0 = 80
  • => 2x = 80
  • => x = 40

To find y, let's use any equation in the "we know that" section.

  • => 40 - y = 18
  • => 40 - 18 = y
  • => 22 = y

Now, let's check our work by using the second equation.

Check:

  • x + y = 62
  • => 40 + 22 = 62
  • => 62 = 62 (Proved correct)

Hoped this helped.
