| 00:0-1 | here . Our goal is basically the same as it | |
| 00:02 | was in the previous two examples , since our variable | |
| 00:07 | in this case C . Appears on both sides of | |
| 00:10 | the equation . We want to put our C terms | |
| 00:14 | together on one side of the equation and put our | |
| 00:17 | numbers together on the other side of the equation . | |
| 00:21 | So let's put our seas together on the left side | |
| 00:24 | of the equation . And we do that by subtracting | |
| 00:29 | to see from both sides on the left , we | |
| 00:38 | have three C plus 15 , and on the right | |
| 00:45 | We have negative 12 . Now we want to put | |
| 00:49 | our numbers together on the right side of the equation | |
| 00:54 | And we do that by subtracting 15 from both sides | |
| 01:03 | . On the left , we have three c . | |
| 01:07 | And on the right -12 -15 is -27 . to | |
| 01:15 | get C by itself , just divide both sides by | |
| 01:18 | three and see equals negative nine . |
