Work out the two numbers.
Write your answers on one line.

Answer 1

The first is 3 and the second is 18

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
