| 00:14 | com . In this equation we start by distributing through | |
| 00:21 | the parentheses on both sides . On the left we | |
| 00:30 | get six x minus two . And on the right | |
| 00:36 | we get 10 x plus 15 minus one . Now | |
| 00:44 | here's the most important step before moving on to make | |
| 00:49 | sure that you've simplified both sides of the equation as | |
| 00:52 | much as you can notice that the left side of | |
| 00:56 | the equation cannot be simplified any further , But on | |
| 01:00 | the right , 10 x plus 15 -1 Can be | |
| 01:04 | simplified to 10 x plus 14 . Bring down our | |
| 01:14 | six x -2 on the left side and we have | |
| 01:19 | a setup you should be very familiar with . So | |
| 01:22 | try to finish this problem from here on your own | |
| 01:25 | by clicking the pause button which is located right about | |
| 01:29 | here on your screen , moving our variables to the | |
| 01:37 | left and numbers to the right . We start by | |
| 01:40 | subtracting 10 x from both sides . On the left | |
| 01:48 | we get negative four X minus two . And on | |
| 01:53 | the right we get 14 and to to both sides | |
| 02:03 | , And we have negative four x equals 16 , | |
| 02:08 | Divide both sides by -4 , and X equals negative | |
| 02:16 | four . |
