Okay, so we want to solve our following equation for y.
00:04
So let's start by expanding some terms here.
00:07
We want to expand them so we can combine like terms.
00:09
So we'll start by expanding this negative 7.
00:11
We'll leave this negative 2 because we have brackets, and we should multiply out to 6 and then combine like terms first, and then this 9 as well.
00:20
So let's begin.
00:23
So i'll just rewrite what we have here.
00:25
And then 9 times 6, i believe that's 54, and then minus 18, is equal to 7 times 4.
00:36
That's a negative 28y plus 14.
00:40
Then we have minus 2, and then we have 12 y minus 18, minus 4 plus 6y.
00:50
Okay, and now let's see.
00:53
We can, inside of our brackets, let's combine like terms.
00:57
So we have 7 minus 18, that's a negative 11...
