Question

The difference of two numbers is three their sum is 13 find the number

Answer 1

The two numbers are 5 and 8

Explanation:

x-y =3

x+y =13

We can use elimination to solve

x-y =3

x+y =13

-------------------

2x = 16

Divide by 2

2x/2 = 16/2

x = 8

Now we need to find y

x+y =13

8+y =13

Subtract 8 from each side

8-8+y =13-8

y = 5
