Here we have the equation d, our variable d, plus 1 .3619, so 1 and 3 ,61910 ,000 equals 2 .0148 ,000.
00:18
Okay, so we want to undo whatever operations are happening to d, so currently 1 .3619 is being added to d, so i'm going to subtract 1 .3619.
00:30
Do that for both sides of the equation.
00:33
3, 6, 1, 9.
00:37
And so we end up on this side of the equation, on the left side, with d plus 0, because we subtracted that out.
00:45
So i'm just going to say d.
00:47
And then i have to do some subtraction here.
00:50
So 8 minus 9, i can't do that.
00:52
I need to borrow.
00:53
So this is going to turn to 3.
00:55
18 minus 9 is 9.
00:57
3 minus 1 is 2...
