In order to solve the system of equations, i will be using the elimination method.
00:06
Now, the elimination method, i need opposite coefficients.
00:10
And looking at my two equations, i do not have opposite coefficients.
00:15
The y variable does have a negative and a positive, though.
00:18
So i'm going to work off of that.
00:20
I'm going to multiply my top equation by 4 and my bottom equation by 6.
00:28
Now notice what happens when i go ahead and i distribute all the fours to each term and the six to each term as well.
00:41
I'm going to rewrite that off to this side.
00:44
So that gives me 12x minus 24y equals 8 and then 30x plus 24y equals 6.
01:00
Look what happened.
01:01
I now have opposite coefficients.
01:04
I have a positive 24y and a negative 24y.
01:08
So now when i go to use the elimination method, these will cancel out...
