Problem we're being asked to determine if the given equation is an identity, a conditional equation, or a contradiction.
00:07
And the only way to determine that is to go ahead and start solving it.
00:11
So first thing is we need to remove all these parentheses.
00:14
So on the left -hand side, we'll distribute the four.
00:16
Well, four times x is four -x.
00:19
Four times seven is 28.
00:22
On the right -hand side, we'll start by distributing the two.
00:25
Two times x is two -x.
00:27
Two times 12 is 24.
00:30
We're going to distribute the two again, two times x is 2x, and 2 times 1 is positive 2...
