As per given by the question,
There are given a equation is,
Now,
For equation x+3=2
According to question, we will need to one tile for each number, variable and sign.
Here,
Suppose one positive x is one tile.
Now,
If there are represent (+1), then they are represent one tile.
If there are represent (+2), then they represent two tile, and
If there are represent (+3), then they represent three tile.
So,
Here, given +3, then they represent three tile.
Now,
There are also given 2.
So, according to question, we will need to one tile for each number, variable and sign.
So,
Here given number is 2, then they represent two tile.
Now,
Hence, the total number of tile that will be use in equation x+3=2 is 6.
