| 00:19 | we're going to use both the distributive property and combining | |
| 00:22 | like terms . But before we do anything we need | |
| 00:26 | to change these minus signs too . Plus negatives . | |
| 00:34 | Now we can distribute the four through the first set | |
| 00:36 | of parentheses And the -3 through the second set of | |
| 00:42 | parentheses . That gives us four times two X . | |
| 00:48 | Or eight X . Plus four times y . or | |
| 00:53 | four y plus negative three times three X . Which | |
| 00:59 | is plus negative nine X . Plus negative three times | |
| 01:04 | negative four Y . Which is plus 12 Y . | |
| 01:09 | Now we can combine like terms eight X . Plus | |
| 01:13 | negative nine X . Is negative one X . And | |
| 01:17 | four y plus 12 y . Is Plus 16 . | |
