| 00:14 | com Notice that there are two fractions in this equation | |
| 00:21 | . In this situation you would definitely want to get | |
| 00:24 | rid of the fractions as soon as possible . and | |
| 00:27 | since both fractions have a denominator of two , we | |
| 00:31 | get rid of those fractions by multiplying both sides of | |
| 00:35 | the equation by two . Now here's what you have | |
| 00:44 | to watch out for . There are two terms on | |
| 00:47 | the left side of the equation , so this too | |
| 00:51 | must distribute through both terms two times 1/2 m is | |
| 00:59 | just M and two times negative five is negative 10 | |
| 01:06 | . So we have M -10 on the left side | |
| 01:09 | of the equation On the right side , R 2's | |
| 01:12 | cancel And we're left with -3 . Now , to | |
| 01:18 | get in by itself , we just add 10 to | |
| 01:22 | both sides of the equation and M equals seven . |
