Question

two numbers differ by 3. the sum of greater number and twice the the smaller number is 15.find the smaller number ​

Answer 1

Answer:

smaller number is 4

Step-by-step explanation:

let x > y

x - y = 3

=> x = 3 + y                  ------------------(1)

x + 2y = 15                   ------------------(2)

now, substituting (1) in (2)

=>3 + y + 2y = 15

=> 3y = 12

=>  y = 4

∴ the smaller number is 4 .

Answer 2

Answer:

4

Step-by-step explanation:

Let the 2 no.s be x and y respectively .

A/q => x - y = 3, ......eq.1

x + 2y = 15; ......eq.2

On solving equation 1 ad 2 ,

We get y = 4 and x = 7 .

Hence 4 is the smaller number.
