Question

The sum of two numbers is 13
and thier difference is 3 whats the anwser

Answer 1

Answer:

The two numbers are 14.5 and 11.5

Step-by-step explanation:

Let the 2 numbers be x and y ;

so,

it is given that :

x+y = 26

x= 26-y (eq. 1)

also according to question

x-y = 3. (eq. 2)

using eq. 1 in 2 we get ;

=> 26-y-y = 3

=> 26-2y=3

=> -2y=3-26

=> y=23/3 = 11.5

now ,

=> x+11.5 =26

=> x= 26-11.5

=> x=14.5

Hence the 2 numbers are x=14.5 and y=11.5

Answer 2

Given,

The sum of two numbers is $13$ and their difference is $3$.

Let two numbers be $a,b$

Sum of two numbers $= a+b=13$_______(1)

Difference of two numbers $= a-b=3$_____(2)

Subtract equation(1)and (2)

$a+b-a+b=13-3$

$2b=10$

$b=5$

Substitute $b=5$ in equation (1)

$a+5=13$

$a=13-5$

$a=8$

Therefore, the values of $a,b$ is $8$ and $5$.
