First equation is: x - y = 12
x = 12 + y
Now, substitute this in 2nd equation,
2x - 3y = 27
2(12+y) - 3y = 27
24 + 2y - 3y = 27
-y = 27 - 24
y = -3
In short, Your Answer would be -3
Hope this helps!
Answer:
Red=6
Yellow=4
Blue=2
Green=8
Total=20
Probability for Red = 6/20 = 3/10
Probability for Yellow = 4/20 = 1/5
Answer:
6/40 = cranberry juice, 30/40 = apple juice , 4/40 = orange juice
if you want to simplify these you can also write them as :
3/20 = cran. juice , 3/4 = apple juice, 1/10 = orange juice.
