Question

The sum of two numbers is 18 and the difference is 10. What are my two numbers?​

Answer 1

The two numbers are 14 and 4

Explanation:

Let x and y be the two numbers

x+y = 18

x-y = 10

Add the two equations

x+y = 18

x-y = 10

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

2x = 28

Divide by 2

2x/2 = 28/2

x = 14

Now find the other number

x+y =18

14+y = 18

y = 18-14

y=4

The two numbers are 14 and 4
