In this problem, we're going to go ahead and solve this two -sip equation for the variable j.
00:06
And we're going to do that by using two properties, the addition property of equality, and the division property of equality.
00:14
These properties basically state that whatever you do to one side of the equation, you have to do to the other side.
00:20
So let's go ahead and take a look at the solving for 7 .j first.
00:24
We have this minus 8 here.
00:25
We want to get rid of it.
00:27
To get rid of it, we do the opposite, and we add 8, because minus 8.
00:31
8 and adding 8 kind of cancel each other out.
00:33
We do this to both sides because of the addition property of equality.
00:37
This keeps the equation balanced and true.
00:39
So the minus 8 and plus 8 go away.
00:42
They're gone.
00:43
They make zero...
