Two and Three step equations - De'Aujanae Allen Flashcards

1

what does it mean when you have a solution of 0=0 ?

2

you can only plug in to an original equation once you have found two variables

3

7x-12y=11 2x+3y=16

4

-r-3s+t=-21 -6r+3s-t=21 -4r+3s+5t=3

5

2x-5y+2z=7 -3x+5y-z=-13 5x-5y-z=25

6

when having two boxed equations you stack them

7

9x-4y=-20 -3x+4y=20

8

-2x-4y=-2 -8x+4y=8

9

is it better to stack equations that contain like terms or not ?

10

which order pair structure is more accurate
