My goal here is to isolate the variable, which in this case is x.
00:08
So i do that by using the opposite operation.
00:11
So i'm going to add 8 .4 to both sides.
00:15
Sorry, i just didn't get the decimal there.
00:17
So that was negative 2 .1.
00:20
On the left side, those give me zero.
00:23
So i'm isolated my variable, which is just x.
00:26
On the right hand side, if i add those two, i'm going to always, when i have one positive and one negative, i'm always going to write the larger absolute value...
