Answer:
Largest Number = a = 7
Smallest Number = b = 4
Step-by-step explanation:
Largest Number = a
Smallest Number = b
a + b = 11
a + 2b = 15
(a + 2b) - (a + b) = 15 - 11
a + 2b - a - b = 15 - 11
b = 4
a + 4 = 11
a = 11 - 4
a = 7
The required numbers are 4 & 7.
Step-by-step-explanation:
Let the smaller number be x.
And the greater number be y.
From the first condition,
Sum of two numbers is 11.
∴ x + y = 11
⇒ x = 11 - y - - - ( 1 )
From the second condition,
Sum of twice the smaller number & greater number is 15.
∴ 2y + x = 15
⇒ 2y + ( 11 - y ) = 15 - - - [ From ( 1 ) ]
⇒ 2y + 11 - y = 15
⇒ 2y - y = 15 - 11
⇒ y = 4
By substituting y = 4 in equation ( 1 ), we get,
x = 11 - y - - - ( 1 )
⇒ x = 11 - 4
⇒ x = 7
∴ The required numbers are 4 & 7.
