The answer is x=2
8-3x=2
You minus 8 from each side=-3=-6
You then divide -6 by -3=2
A negative number divided by a negative number stays negative.

Answer: 8- 3x = 2 will be the answer.

Explanation:

let us consider the number is x .

so, the three times of the number= 3×x=3x

when eight  decreases by this three times of the number then its expression = 8-3x

And, according to the question, this expression is equal to two.

Thus, 8-3x=2, where x=2.( because, 8-2=3x⇒6=3x⇒x=2)
