Answer 2

Given data: sum-17 and difference-7

To find: Two numbers

Solution:

• Addition is defined as the sum of two numbers.
• Subtraction is define as the difference of two numbers.
• According to the arithmetic rule, a + b = c and a - b = c.
• Let the 2 numbers be a and b. Now according to the given statement a + b = 17 and a - b = 7.
• Equating the given 2 equation we get 2a = 24 (+b and -b will be cancelled). The value of a = 12.
• Substitute the value of a in any equation we will get the value of b ( 12 + b = 17). The value of b = 5.
• Hence the two numbers are 12 and 5.
