| 00:0-1 | in this problem we are asked to solve the following | |
| 00:02 | equation and check your solution To a plus five equals | |
| 00:07 | 17 . To solve this equation for a , we | |
| 00:11 | must first isolate the term containing A . Which in | |
| 00:15 | this case is to A . Since five is being | |
| 00:18 | added to to A . We need to subtract five | |
| 00:21 | from both sides of the equation . Yeah , On | |
| 00:25 | the left side of the equation , the positive five | |
| 00:28 | and -5 cancel each other out . And we have | |
| 00:31 | to a . And on the right side of the | |
| 00:34 | equation 17 -5 is 12 . So we have to | |
| 00:38 | a equals 12 . Now to get a by itself | |
| 00:42 | , since A is being multiplied by two , we | |
| 00:45 | need to divide by two on both sides of the | |
| 00:48 | equation , On the left side of the equation , | |
| 00:51 | the two's cancel . And we have a . And | |
| 00:54 | on the right side of the equation , 12 divided | |
| 00:57 | by two is six , So a equals six which | |
| 01:01 | is the solution to our equation . To check our | |
| 01:04 | solution , we plug six back in for a in | |
| 01:07 | the original equation . So we have two times six | |
| 01:12 | plus five equals 17 , two times six is 12 | |
| 01:18 | , and we have 12 plus five equals 17 or | |
| 01:22 | 17 equals 17 , which is a true statement , | |
| 01:27 | so our answer checks . |
