What two numbers add up to 14 but when substrates, they equal 2

Question

1. Name the equations the add up to 14.

2. Then subtract the sum from the largest number to find the different 

3. Which one equals 2?

Answer 1

8+6 = 14

8-6 = 2

The numbers are 8 and 6 ....

 

But.. Let's set up the equations

 

x+y=14   {equation 1}

x-y=2      {equation 2}

-------------    add the equations

2x = 16

x = 8

 

8 -y = 2

y=6

 

The numbers are 8 and 6
