Question

The sum of two numbers is 30. Their difference is 6. What are the numbers?

Answer 1

Answer:

sum of two numbers = 30

difference between two numbers = 6

let the numbers would be x & y.

so, from the given information we get two equations.

x + y = 30 .... ( 1)

x - y = 6 .... ( 2)

2x = 36 .... { by adding ( 1) & (2) equations}

x = 36/2

x = 18

by putting value of x in ( 1) equation.

x + y = 30

18 + y = 30

y = 30 - 18 = 12

so, the numbers are 18 & 12.

hope it will help you.
