I found #n=14#

Explanation:

Here you want to find the value of #n#.
So, try to "isolate" it on one side (say, the left) taking all the numbers to the other side of the #=# sign.

To do that you must always balance your equation so that your "balance" is always in equilibrium!

For example: you can take #3# to the right BUT remember the it was multiplying on the left so you must change into a division to move it to the right:
#n/7=6/color(red)(3)#
Same thing with #7#; it was divided on the left so it ends up multiplying on the right:
#n=color(blue)(7)*6/color(red)(3)#
so:
#n=7*2=14#

hope it helps!
