Today we'll be working on the problem 3 minus 3 .7b is equal to 10 .3b plus 10.
00:21
Remember, with algebra, whatever you do to one side, you have to do to the other side.
00:26
Now let's put all the numbers here and all the letters, the variables here.
00:34
So to do that, we would have to multiply, i mean add both sides by this.
00:40
Right here, 3 .7b, if you want to get rid of the b.
00:44
So plus 3 .7b to both sides, right here, and to right here.
00:52
And that would give us, well, 3 .7b minus 3 .7b is equal to 0, because whatever subtracted by itself is equal to 0.
01:03
So giving us just 3 is equal to 10 .3b plus 10 plus 3 .7b.
01:15
So let's combine the like terms first.
01:19
10 .3b plus 3 .7b.
01:26
Now if you do the math, 3 .7, you add.
01:31
That would give you 10...
