Question

7. The sum of two consecutive natural numbers
is 79. Find the two numbers.
(Hint: If x is one of the numbers then the
consecutive number is.+ 1.1​

Answer 1

Let the number be = x

Its consecutive number = x + 1

sum = 79

x + x + 1 = 79

2x + 1 = 79

2x = 79 - 1

2x = 78

x = 78/2

x = 39

x+ 1 = 39 + 1 = 40

The numbers are 39 and 40
