Question

When three times a number is decreased by two, the result is 34. What is the number?​

Answer 1

12

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

`(3x)/(3)`
`(36)/(3)`

the answer is:

x=12

Answer 2

The answer is 12.
12*3=36
36-2=34
