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 minus one can | |
01:04 | be simplified to 10 X plus 14 . Bring down | |
01:13 | our six x -2 on the left side and we | |
01:19 | have a setup you should be very familiar with . | |
01:22 | So try to finish this problem from here on your | |
01:25 | own by clicking the pause button which is located right | |
01:29 | about here on your screen , moving our variables to | |
01:36 | the left and numbers to the right . We start | |
01:40 | by subtracting 10 x from both sides . On the | |
01:47 | left we get negative four X minus two . And | |
01:53 | on the right we get 14 and to to both | |
01:59 | sides , And we have negative four x equals 16 | |
02:08 | , Divide both sides by -4 , and X equals | |
02:15 | negative four . |
