6x = 18

x = 3

So numbers will be 3 , 21

Answer 2

Answer:

Two numbers are 21 and 3.

Step-by-step explanation:

It is given that one number is 7 times another and their difference is 18.

We need to find the two numbers.

Let smaller number be x.

One number is 7 times another, So the greater number is 7x.

The difference of these two number is 18, so

$7x-x=18$

$6x=18$

Divide both sides by 6.

$x=\frac{18}{6}$

$x=3$

The smaller number is 3 and the greater number is

$7x=7(3)=21$

Therefore, the two numbers are 21 and 3.
