So here we have negative 3n minus 1 3rd equals 8 thirds.
00:10
Let's go ahead and add 1 3rd to cancel out subtraction.
00:16
It's nice we have a common denominator.
00:19
So negative 3n equals 9 thirds.
00:22
You just add the tops from the bottoms are identical.
00:26
9 divided by 3 is equal to 3.
00:28
So i can just convert 9 thirds down to 3.
00:33
And then divide both sides by negative 3, and you get n equals negative 1.
00:40
Negative 1 can be plugged back in to double check your answer.
00:45
So i place n with negative 1.
00:48
So i have negative 3 times negative 1 minus 1 3 3 3 equals 8 thirds...
