Greater number = 7 , Smaller number is 4

Step-by-step explanation:

Let the first number is x

Second number is x-3

Given condition is x+2(x-3)=15

===>>> x+2x-6=15

===>>>3x=21

===>>>x=7

First number is 7 and the second number is 4

Answer 2

Answer:

4

Step-by-step explanation:

Let the greater number be x and smaller number be y

x-y =3    ...................(1)

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

x=15-2y     ..............(3)

Substitute 3 in 1

15-2y-y =3

15-3y=3

-3y = -12

therefore y =4

to find greater number:

{substitute value of y in (1)

x-4 = 3

therefore x=3+4=7}

Hope this helps:)
