X+y=12
Get the y alone, so subtract x by each side to get y= -x+12
Then fill in the equation: 4x + (-x+12)=33, remove the parenthesis and solve to get 3x+12=33. Then subtract 12 from both sides to get 3x=21. Now divide 3x from both sides to get x=7 now, use this x answer for the previous equation, x+y=12. Fill in the x so now it’s (7) + y=12
And then subtract 7 from both sides to get y=5. So for the first slide, x=7 and y=5
For the next slide, you already have y= -x+15. Fill this in for the equation 3x+2y=36. 3x+2(-x+15)=36 distribute to get 3x+-2x+30=36. Subtract the x’s to get an equation of x+30=36. Subtract 30 from both sides to get x=6 and use this for the other equation, y= -x+15 to get y= -6 + 15, which equals y=9. x=6 and y=9
I hope this helped!

1. SCR (or PPW). 43 more flavors
2. GLT. 41,976 notebooks
Step-by-step explanation:
1. Conceptual key: SCR
Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...
37 + x = 80
x = 80 -37 = 43
Lizzy needs to create 43 more flavors.
__
Additional comment
This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.
_____
2. Conceptual key: GLT
There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.
(212 boxes)(198 notebooks/box) = 41,976 notebooks
