Answer:
It’s 5
Step-by-step explanation:
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=
Also y=
We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
Answer:
There is a 20% probablity that the marble will be green :)
