Answer:
The value of x that makes the equation true is 3

Explanation:
From the attached image;
Let us write the mathematical equation of the model.
The long bar means x, while the small squares have a value of 1 each.

solving the equation we have;

Therefore, the value of x that makes the equation true is 3
82.15 / 31 = 2.65 per gallon
4 people x 45 minutes = 180 minutes total to paint 5 walls
180/5 = 36 minutes of man work per wall
36 * 4 walls = 144 total minutes
144/6 people = 24 minutes total
you will have 8 tables so
72 chair / 8 tables = 9 chair per table
