Here we have the equation, c plus three -fourths equals negative one -fourth.
00:09
So if i visualize what's happening there on the number line, i was at c, i added three -fourths, and i ended up at negative one -fourth.
00:21
So to undo that, i need to subtract three -fourths.
00:27
Okay, so i'm going to subtract three -fourths from both sides.
00:33
There we go.
00:36
So i'm going to end up with c on this side, 3 fourths plus negative 1 or minus 3 fourths is going to be 0.
00:45
So you're c plus 0.
00:47
But we don't need to write that because plus 0 doesn't change anything.
00:50
And we end up with on this side, negative 1 4th or minus 3 4ths, which is negative 4ths, which is the same thing as negative 1...
