Question

The sum of two numbers is 21 the second number is six times the first number

Answer 1

let the numbers be x and y

so,

x+y = 21

x = 6y

then putting it in the 1st equation,

y = 3

and x = 18

hope this helps you out!

Answer 2

Step-by-step explanation:

Given: The sum of 2 numbers is $21$, and the second number is 6 times the first number.

To find: The solution to the above problem.

For calculation of the above equation,

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

We know that $x+6x=21$

⇒ $x+6x=21$

⇒ $7x=21$

⇒ $x=\frac{21}{7}$

⇒$x=3$

Now, the second number is,

⇒ $6x =$ second number.

⇒ $6$ × $3$

⇒ $18$

The first number is $3$ and the second number is $18.$
