Answer:

12

Step-by-step explanation:

The equation can be represented by this, with x equaling "the number":

3x-2=34

    +2 +2

We are trying to isolate the x, so we can add 2 to both sides, to keep the equation equal.

3x=36

Now we have to divide both sides by 3 to isolate the x

[tex]\frac{3x}{3}[/tex]   [tex]\frac{36}{3}[/tex]

the answer is:

x=12
