Question

2 numbers differ by 3. The Sum of the greater number & twice thesmaller humber is 15 find the numbers. ​

Answer 1

Answer:

Let, two numbers be x & y

A/C to 1st condition.

x- y = 3

A/C to 2nd condition

x + 2y = 15

by solving simultaneously method

x= 7

y= 4

The two numbers is (7,4)

Answer 2

Answer:

A = 7 and B = 4

Step-by-step explanation:

a = smaller number

b = greater number

a - b = 3                   (1)

a + 2b = 15              (2)

  a + 2b = 15

-  a  -  b    = 3

  (-)  (+)     (-)

=      3b   = 12

       

b=12 / 3

b = 4

substitute b = 4 in (1)

a - b = 3

a - 4 = 3

a = 3 + 4

a = 7

Hence a = 7 and b = 4

To recheck if the numbers are correct

a - b = 3

7 - 4 = 3

a + 2b = 15

7 + 2(4) = 15
