twice the smaller number is 15. Find both the numbers.​

Answer 1

Answer:

let the greater no.and smaller no. be x and y respectively

x-y. =3. (1)

x+2y=15. (2)

- -. -

-3y=-12

3y=12

y=4

then put in (1)

x-4=3

x=1

Answer 2

Answer:

greater number=7

smaller number=4

Step-by-step explanation:

x-y=3        (equation 1)

x+2y=15    (equation 2)

subtracting both the equations

x -y   =3        

x+2y=15

-  -     -

-3y=-12

  y=4

substitute in equation 1

x-4=3

x=7
