The first thing i want to do on this problem is combine my like terms on the right side.
00:09
Let me just write this first.
00:14
I always look to see if there are terms i can combine on one side of my equal sign.
00:19
So two -fifths plus two -fist gives me four -fifths.
00:28
Next, i want to move my variables to combine those into one -like term, but they're on different sides of my equal signs.
00:34
I'm going to use the opposite operation here and add two -sev.
00:38
Five -sevths plus two -sevs gives me seven -sevths, but i know seven -sides.
00:42
Sevens is the same as one x, which is just x.
00:45
So i get x plus one third equals four fiss.
00:49
Next, i have to subtract one third because that would be the opposite of adding one third.
00:54
My goal is to isolate the variable.
00:56
So four fiss minus one third.
01:00
I'll just do that work over here.
01:01
I need a common denominator...
