Question

The product of nine and a number is added to 6, the result is 24. What is the number? Which of the following equations could be used to solve the problem?

Answer 1

The number is 2.

The expression is
`9x+6=24`

Explanation:

Let the number be x.

The product of 9 and this number is
`9x`.

When we add this to 6, we obtain

`9x+6`

The result being 24, gives us the equation;

`9x+6=24`

Group similar terms;

`9x=24-6`

`9x=18`

Divide both sides by 9.

`x=2`
