c+1=0 or c+9=0
c=−1 or c=−9
C= -1 OR C= -9
Answer:
=
* 2 + 
Step-by-step explanation:
lets start with what we know.
the recipe calls for 2
cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2
2
* 2 = 5 cups of yogurt.
the total of yogurt and oats is
and we know how much yogurt we have so we subtract that from the total of both.
- 5 = 
the oats after doubling were
cups so u divide it by 2
/ 2 =
before doubling
B. because you are still multipying they just broke it down (7*24)= 168 , and b also = 168
