Okay, solve each equation for y, then find the value of y for each value of x.
00:08
So first it says, find the equation for y, meaning get y by itself.
00:15
So we're going to do that over here.
00:16
I'm going to rewrite it.
00:20
I'm going to box what i'm solving for, so that's y.
00:26
To get y by itself, the first thing i'm going to do is subtract 3x from both sides.
00:34
That leaves us with negative 5y.
00:36
Forget this negative sign here.
00:38
We didn't take anything away from that.
00:41
9 minus 3x.
00:43
We just write it.
00:44
As we see it, they're not like terms, so we can't combine.
00:48
Still solving for y.
00:50
The only thing that's left is that negative 5, which i'm going to divide by, but divide by everything.
00:59
So my new equation is 9 divided by negative 5.
01:05
I have the negative out front.
01:07
And negative 3, negative 3 .5 ,000.
01:09
3 divided by negative 5 makes it positive 3 over 5, and we still have that x.
01:20
So now it's saying, find a value of y for each value of x, and these are the xes we have here...
