Here we have the equation 2 9th times x equals negative y.
00:07
Okay, we know that y is a positive number, y is greater than 0, and we're wondering if x is positive or negative.
00:15
So if we look at how this equation is laid out, we have 2 .9th, which is a positive number.
00:21
So i'll use this highlighted to show that.
00:22
So 2 9s is our positive.
00:24
X, we don't know what x is that we're looking for, and x is equal to negative y.
00:29
So if y is a positive number, then negative y must be a negative number.
00:34
So equals negative.

I'm going to use blue.

Nope, that was not my highlighter...
