​

Answer 1

Answer:

Step-by-step explanation:

Given

Number of rooms on the first floor =x

Twice the number of rooms on the first floor =2x

We know that the word 'less than' a number means 'subtracting' it from a number.

12 less than the number of rooms on the first floor =2x−12

∴ Number of rooms on the ground floor of a building =12 less than the number of rooms on the first floor

                                                                                        =2x−12

Answer 2

Given
Number of rooms on the first floor =x
Twice the number of rooms on the first floor =2x
We know that the word 'less than' a number means 'subtracting' it from a number.
12 less than the number of rooms on the first floor =2x−12
∴ Number of rooms on the ground floor of a building =12 less than the number of rooms on the first floor
=2x−12 Please mark me brainlist
