the sum of 2 numbers is 11 and there difference is 3

Question

what are the 2 numbers?????????

Answer 1

Let's say the 2 numbers are x & y

So the sum of 2 number is x + y = 11

and there difference is x - y = 3

now add both the equations

x + y = 11

x - y = 3

2x = 14

x = 7

Keep the value of x in any equation 7 + y =11

y= 4

So the two numbers are 7 & 4
