Okay, so it says to solve each system of equations.
00:04
So i have x minus y over 2 equals negative 2.
00:09
And then i have 0 .01x plus 0 .02y equals 0 .03 .3.
00:18
So the first one i'm going to do is i'm going to get y by itself for both of them.
00:26
So if i have y equals y over 2 or negative y over 2 equals negative y over 2 equals negative x minus 2, i'm going to multiply both sides by a negative 2.
00:45
So i would have y equals 2x plus 4.
00:53
And then for this one, if i get y by itself, i'll have 0 .02y equals negative 0 .01x equals 0 .03.
01:12
And if i divide both sides by 0 .02, oops, plus, that should be plus 0 .03, 0 .02.
01:23
So then i have 0 .01 divided by 0 .02 is one half.
01:36
So y equals 1 half x plus 0 .03 divided by 0 .02 by 3 over 2, which is 1 .5.
01:51
So i'm going to change this to y equals 0 .5x plus 1 .5.
01:58
And actually that's a negative 0 .5 .5.
02:00
0 .5.
02:01
So i'm going to have negative 0 .5x plus 1 .5 equals 2x plus 4...
