Question

The first number in two numbers is five times that of the second number by adding 21 to each number the first number double the second number. Find the number

Answer 1

Step-by-step explanation:

let one number=x

therefore, other number=5x

atq

2(x+21) = 5x+21

2x+42 = 5x+21

5x-2x = 42-21

3x=21

x =21÷3

x=7

therefore

first number =x=7

second number =5x=5×7 =35
