In this question we are given an equation that tells us 1x plus 5 plus 1x minus 5 equals 1x plus 10.
00:24
We need to solve for x.
00:26
What i want to do on the left side is combine like terms.
00:29
That means i'm going to combine those two 1x's.
00:34
So 1x plus 1x gives us 2x.
00:38
And then i'm going to combine the positive 5 and the negative 5.
00:42
In other words, that is 0.
00:47
So i don't really need to write that, but i'm just going to write it to show that positive 5 and negative 5 equals 0.
00:52
Alright, that is going to be equal to 1x plus 10.
00:59
Alright, so i want to get all of the x's on the same side.
01:02
So i need to subtract 1x from each side.
01:09
That's the same as adding a negative 1x...
