In this problem, what we're being asked to do is to come up with an equation that we represent a contradiction.
00:07
Well, let's keep in mind what a contradiction is.
00:10
Well, think about what the word contradict means.
00:12
It means that it doesn't make sense.
00:14
So in other words, when we solve equations that are contradictions, that means that they have no solution to them.
00:23
So we have to think of why an equation would have no solution.
00:27
Well, that means when i substitute a value in for x, initially it's going to look like we're going to have the solution.
00:32
Same thing, but then we either add or subtract different values to it...
