| 00:0-1 | in this equation we have several fractions to deal with | |
| 00:04 | . But more importantly notice that the denominators of these | |
| 00:08 | fractions are different in this situation . In order to | |
| 00:12 | get rid of the fractions , we must multiply both | |
| 00:16 | sides of the equation by the common denominator for these | |
| 00:19 | fractions . The common denominator for 2 , 5 and | |
| 00:25 | 10 is 10 . So in this equation to get | |
| 00:30 | rid of the fractions we multiply both sides of the | |
| 00:33 | equation by 10 , Make sure you distribute the 10 | |
| 00:43 | through both terms on both sides of the equation . | |
| 00:49 | Mhm . When we multiply 10 times em over to | |
| 00:55 | the 10 and two reduced to five and one . | |
| 00:58 | So we have five times M Which is five M | |
| 01:04 | . When we multiply 10 times 8/5 , the 10 | |
| 01:09 | and five reduced to two and one . So we | |
| 01:12 | have two times eight which is positive . 16 . | |
| 01:17 | Yeah , On the right , 10 times four is | |
| 01:22 | 40 . Oh . And when we multiply 10 times | |
| 01:27 | negative 3/10 M are tense cancel . And we're left | |
| 01:31 | with negative three M . Now let's move our ems | |
| 01:37 | to the left and numbers to the right By 1st | |
| 01:41 | adding three M . To both sides , And we | |
| 01:49 | get eight m . Plus 16 equals 40 . Now | |
| 01:57 | we move our numbers to the right by subtracting 16 | |
| 02:02 | from both sides , And we get eight m equals | |
| 02:09 | 24 Divide both sides by eight , and M equals | |
| 02:17 | three . |
