Question

If 6 is subtracted from 3 times a certain number, the result is 84. Find the number.

Answer 1

Answer:

30

Step-by-step explanation:

So to do this you would set up the equation $3x-6=84$ than you would add 6 to both sides so you would get $3x=90$ than you would divide 3 from both sides so $x=30$ and that is the final answer which is correct

Answer 2

3x-6=84
3x=90
x=30
The number is 30.
