Its 9 (again!)
3 times 9 = 27 minus 5 = 22

this is a pretty straight forward problem. you have to isolate the x, so, first move the -5 to the other side of the equation by adding 5 to both sides: 3x-5+5=22+5 which leaves you with 3x=27
then divide each side by 3, leaving you with x=9
hope this helps

3x-5=22
--
3x=27 (add the 5 to both sides the 5 and -5 cancel out and 22+5 is 27)
--
So 27=3x; divide each side by 3, the 3 and 3 cancel out, and 27 divided by 3 is 9. x=9

3x-5=22

3x=27

yes, you need to solve for X.
3x - 5 = 22
you need to isolate the X, so move 5 over to the other side by adding 5 to 22. (you have to cancel out the signs, + or - )
now
3x = 27
to get X by itself, divide both sides by 3
x = 9
There's your answer.
Understand how I did it?

Isolate the variable. Add 5 to each side then divide by 3

Just isolate the "X"
One step at a time
1. add 5 to both sides
2. Then divide by 3 on both sides
