Question

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

Answer 1

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

Answer 2

30

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
