Okay, so here we have a slightly more challenging absolute value problem.
00:05
We've got absolute value of 5 minus 4x inside our absolute value minus 3 equals 4.
00:16
So here we have to isolate the absolute value first.
00:20
We're actually going to add 3 to both sides, so we get this absolute value all alone on the left -hand side.
00:28
4 plus 3, we'll give us 7.
00:31
Now that the absolute value is isolated, we have to stop and think.
00:35
Can an absolute value equals 7? the answer is yes, 7 is a positive number.
00:40
It's not negative.
00:41
So we make a split.
00:44
Drop the absolute value if it wasn't that.
00:47
Drop the absolute value, but negate the other side.
00:53
Now we're just solving these two linear equations.
00:56
It's a little trick here because we have some negative...
