PLEASE HELP!!!!!!!!!! im stuck

Answer 1

There are 3 chairs in one row.

Explanation:

Let
`$ x $` be the number of chairs in one row. That is the length of one row.

Now, from the given data, two rows of length
`$ x $` can be formed with one chair left.

Or, if 17 extra chairs given, we can form 8 rows of the same length.

This means that there are
`$ 2x + 1 $` chairs in the first case. And since with 17 extra chairs we can form 8 rows, the equation would be
`$ (2x + 1) + 17 = 8x $`

Solving this for '
`x`' we get,

`$ 2x + 18 = 8x $`

`$ \implies 18 = 6x $`

`$ \implies x = 3 $`

Therefore, the length of each row is three.

That is, there are three chairs in one row.
