So if i solve all of these equations for y, on the first one, i'm going to get two answers.
00:07
I'm going to get y equals negative x and y equals x over 2.
00:19
With the second equation, i'm going to get y equals negative 1 minus 6 over x.
00:30
So when i look at these, i'm going to sub both of these in for y.
00:36
So if i have negative x equals negative 1 minus 6 over x, you can add 1.
00:48
So negative x plus 1 equals negative 6 over x.
00:56
And if i divide, if i multiply both sides by x, i'd get negative x squared plus x equals negative 6, negative x squared plus x plus x is zero so then i would factor both of these before i did actually i'm to take that negative out so if i did that's going to make this a negative and this a negative so i would need x and x positive instead of a negative 3 positive 2 so x could be three or two.
01:50
So i put that back in there.
01:52
Then if that's the case, y is going to be negative three and negative two.
01:59
So for that first part, my answers would be x is negative two.
02:11
Sorry, x is two...
