X = 5; 2(5) - 1 = 9. 4(9) = 36
2(w-8) = 9. Hope it helps!
I’d say around 75% or less
This is just an assumption considering that there are more red than blue but only trumps blue by 2. Taking out those two, you’d be left with a 50% chance of getting red and/or blue marbles
X=3
Y=-8
Z= 1
hope that helps
