We're being asked to solve the given equation for z.
00:03
Well, the first thing i noticed is that we have parentheses.
00:06
So we have to remove those by using the distributed property.
00:09
So let's start with the three.
00:10
Well, three times 2z is 60.
00:13
Then we have 3 times negative 6, which is negative 18.
00:17
Now we distribute the negative 4.
00:19
Negative 4 times 3z is negative 12 z, and negative 4 times 1 is negative 4.
00:25
We're going to bring down the equals 5.
00:27
Now we distribute the negative 2.
00:29
Negative 2 times z is negative 2 z and negative 2 times 1 is negative 2.
00:35
Now on the left hand side, i see we have like terms.
00:38
So let's combine them.
00:40
We have 6z minus 12 z.
00:42
That's negative 60.
00:44
And then we also have negative 18 minus 4, which is negative 22...
