Answer:
The answer is 7 cups
Step-by-step explanation:
1 cake-2 2/6 cups
Which can also be written as
1 cake-14/6 cups
3 cakes-x cup
Cross multiply
x=14/2
x=7
Therefore Karen needs 7 cups of flour to make 3 cakes
Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
