Question

How do you write the expression for Fifteen equals three more than six times a number and 6?

Answer 1

`15=3+6x`

or

`15=3+6x+6`

or

`15=3+6x+36`

Read to see how that is

Explanation:

Let the number be `x`

more than is addition(`+`)

times is multiplication(`*`)

So six times a number is `6*x=6x`

Three more than six times a number is `3+6x`

`:.`Fifteen equals three more than six times a number is

`rArr15=3+6x`

With the 'and six', I believe you simply add `6` to the above if it is not together. Meaning we would have;

`15=3+6x+6`

If it is together, then that means six times a number and six would be `6*(x+6)=6x+36`

In that case, it will be `15=3+6x+36`
