Okay, so our problem here is the system of equations.
00:08
3x minus y equals 7.
00:14
And the other equation is 2x plus 2y is equal to 10.
00:25
So to solve this, what we're going to have to do is multiply this top equation by 2.
00:31
So let's do that.
00:32
So 2 times this entire equation give us 6x.
00:39
Minus 2y is equal to 14.
00:43
And if we were to, and then, so this is, let's separate these, and if we were to add these two equations up, we would get 8x, because 2x was 6x, and 2y minus 2y is equal to 0.
01:01
So let's not, let's just leave it like that...
