Question

The sum of two numbers is 11 and their difference is 5. Find the numbers.​

Answer 1

Answer:

Let the numbers be x and y

so

$x + y = 11 \\ x - y = 5 \\ - \: \: \: \: + \: \: \: \: - \\ \\ 2y = 6 \\ y = \frac{6}{2} \\ y = 3$

y=3

so x =

$x + y = 11 \\ x + 3 = 11 \\ x = 11 - 3 \\ x = 8$

So the two numbers are 8 and 3

Answer 2

Answer:

x=8, y=3

Step-by-step explanation:

let two numbers be x and y.

So,

x+y = 11.

and

x-y = 5.

x= 5+y

substituting value

5+y+y=11

5+2y=11

2y=11-5

2y=6

y=3

substituting value of y

x-3=5

x=8.
