So for this problem, we're given the equation negative 9x plus y equals 5.
00:09
And there's two parts to this problem.
00:12
The first part is that they ask us to solve for y, meaning that we have to rewrite the equation so that we have the form y equals whatever we end up getting when we solve for y.
00:27
So if you look at the equation negative 9x plus y equals 5, our goal is to try to get y by itself.
00:35
So in order to do that, i would have to use inverse properties or opposite properties in order to move this negative 9x away from that y.
00:46
So since it's negative 9x, i would have to do the opposite, which is plus 9x.
00:53
And if you recall, the golden rule of algebra is that whatever you do to one side of the equation, you must do it to the right side of the equation.
01:04
So i would have to also add 9x to the right side.
01:12
When i do that, i end up having the negative 9x term and the 9x cancel out.
01:18
So all i have left is y equals.
01:22
And i can't combine 5 with 9x because 9x has a variable while the 5 does not have a variable.
01:30
So i can't combine those.
01:31
So i end up having 5 plus 9x...
