The sum of two numbers is 21.

The second number is six times the first number.

Work out the two numbers.

Write your answers on one line.

The first is 3 and the second is 18

Step-by-step explanation:

Let the first number be x and the second number be 6x

The sum of the two is 21 which means

x+6x = 21

7x=21

Divide both sides by 7

X=3

And the second number is six times the first which means

6 (3) = 18

Therefore, the first number is 3 and the second number is 18
