So, you do the operations on both sides. Subtract 6 from each side first, getting
84-6=6x
which is 78=6x
then, you divide both sides by 6 and you get 
78/6=x
which is 13

x=13

Hope this helped!
you are able to add multiply subtract and divide from both sides of the equation as long as you do it on both sides of the equation. so you want - 6 from both sides

84-6=6x+6-6

78=6x

and then you can divide both sides by 6

78/6 = 6x / 6

which equals

13 = x
