Question

the sum of two number is 11 and their difference is 5. find the numbers​

Answer 1

Given :-

Sum of two numbers = 11

Difference of two number = 5

To Find :-

Numbers

Solution :-

Let the number be x and y

x + y = 11 (1)

x - y = 5 (2)

Add both equations

x + y + x - y = 11 + 5

2x = 16

x = 16/2

x = 8

Using 1

x + y = 11

8 + y = 11

y = 11 - 8

y = 3

Answer 2

Answer:

Step-by-step explanation:

Let x = the larger number

Let y = the smaller number

x + y = 11

x - y = 5

Adding both equations,

2x = 16

x = 8

Substituting the value of x in the first equation,

x + y = 11

8 + y = 11

y = 11 - 8

y = 3
