What your trying to do is find the value of x.....so first you would add 2 to both sides.....
x/6-2=10
+2 +2
x/6=12
So that you get x/6=12.Next u would need to multiply both sides by 6....
x/6=12
*6 *6
x=72
Which would give you your answer x=72.
Hope this helps! And if you need anything else just ask! :)
