| Let's start with distribute, combine and simplify. | |
 | |  |
|

|
The Princess' math problem was.......... 3(x + 2y - z) - 2(3x - y + 3z).
|
|
|
|
| | |
| First, You need to distribute. (3*x=3x.) (3*2y=6y.) (3*-z = -3z. ) | |
| | |
|
|
| | |
| oh!.. I get it! Next, you would have to distribute -2. Right? | |
| | |
|
|
|
|
|
|
|
| | |
| Correct! (-2*3x= -6x.) (-2*-y=2y. )(-2*3z= -6z.) | |
| | |
|
|
| | |
| I get it! Thanks! Next you would have to combine like terms!.. [3x+(-6x)= -3x] [6y+2y=8y] [-3z+(-6z)= -9z] | |
