Question

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

Answer 1

Answer:

let us assume that small number is b and larger number is a

by given

     a-b=3

then

a+2b=15

by the 2 equations

  a-b=3

  -a-2b=-15

--------------------

= -3b = -12

b = -12/-3

b=4

therefore smaller number is 4

Step-by-step explanation:

Answer 2

Let Greater Number=x

Let Smaller Number=y

Difference=3

MEANS

x-y=3

x=3+y. (Equation 1)

Sum of Greater number(x) and (2y)=15

A/Q

x+2y=15

3+y+2y=15. (x=3+y)

3y=15-3

3y=12

y=12/3

y=4

We get y=4

We know x=3+y

x=3+4

x=7

$\boxed{\mathsf{\huge{Smaller\:Number=4}}}$

$\boxed{\mathsf{\huge{Greater\:Number=7}}}$
