Question

The sum of two numbers is 22, and their differences is 0. What are the two numbers?

Answer 1

Answer:

both the numbers are 11

Step-by-step explanation:

given that

x+y=22----------    (1)

x-y=0 ---------------  (2)

from (2)

x=y

substituting in 1

x+x=22

2x=22

x=$\frac{22}{2}$

x=y=11

Answer 2

Answer:

Let the first no. = X

the second no. = Y

According to question

X + Y = 22 (1)

X - Y = 0 (2)

add both equations 1 and 2

2X = 22

X = 11

put value of X in any of the equation

So value of Y = 11
