Question

The sum of a number divided by 6 and 5 is 7. How do you find the number?

Answer 1

The number is `color(red)(12)`

Explanation:

Let the number be represented by the variable `color(blue)n`

We are told
`color(white)("XXX")color(blue)n/6+5=7`

Subtracting `5` from both sides gives
`color(white)("XXX")color(blue)(n)/6=2`

Then multiplying both sides by `6`
`color(white)("XXX")color(blue)n=12`

Answer 2

I got `12`

Explanation:

I interpreted the question as:

`x/6+5=7`

where `x` is our unknown number.

Solving for `x`:

`x/6=7-5`

`x=6*2=12`

Answer 3

`210`

Explanation:

If you meant a number dividing by `6` then `5` then the answer is `210`. If you don't mean that, I'm very sorry.
Let "the sum of a number" be `x`.
`x` divided by `6` then divided by `5 = 7`
Now, let's work backwards.
Let `y` be the unknown.
`x` divided by `6` is `y`. `y` divided by `5` is `7`
To find `y`, we take `7*5=35`.
Then, to find `x`, we take `y*6`.
`y` is `35`.
`35*6=210`
