We have the equation negative 6 -7s equals negative 3 4ths b.
00:09
So to find b, we want to undo what's happening to it, which is, currently it's being multiplied by 3 -4ths.
00:17
So if i divided by 3 -4ths, that's the same as multiplying by the reciprocal 4 -thirds.
00:23
But notice this was a negative 3 -4th, so we also need a negative 4 -thirds.
00:28
So we end up with just b, not negative b.
00:31
And if we did it on one side, we have to do it to the other side.
00:34
Here we go.
00:36
So let's simplify this a bit.
00:38
So here i have a 4 in my numerator and denominator, and a 3 in the numerator and denominator and 2 negative signs that cancel out and equal a positive.
00:49
Here i have two negative signs that cancel out and equal a positive.
00:54
We also have a 3 in the denominator, which can become 1, and then that changes this to a 2...
