Question

The sum of two numbers is 25. Their difference is 3. What are the numbers?

Answer 1

X+Y=25--------------(1)
X-Y=3------------------(2)
SUBTRACTING (1)AND(2), WE GET:
2X=22,
X=22÷2,
X=11--------------(3)
NOW SUBSTITUTING(3) IN (1), WE GET:
11+Y=25
Y=25-11
Y=14.

THEREFORE, THE TWO NUMBERS ARE 11 AND 14

Answer 2

HIII BUDDY!!!



Let the number be x and y


Now ATQ,




Sum of 2 numbers

$x + y = 25 \: \: - (1)$


Difference of 2 numbers

$x - y = 3$



$= > x = 3 + y \: \: - (2)$


From -(1) and -(2)


$x + y = 25$


Substituting the value of x from-(2)



$3 + y + y = 25$




$= > 3 + 2y = 25$




$= > 2y = 25 - 3$




$= > 2y = 22$




$= > y = \frac{22}{2}$




$= > y = 11 \: \: ans$



As, we know that



$x = 3 + y$



$= > x = 3 + 11$




$= > x = 14 \: \: \: ans$
