Answer:
y=0
Step-by-step explanation:
add 2 to both sides. The -2 on the left side cancels out leaving Y and the -2 on the right side adds to 0
The third one is a point with the first equation.
I had to simplify the second equation.
It simplified to,

The second one with the above is didn't go through so I'd say no solution.
The probability that you will NOT choose a blue marble is 28/45.
45 because there are 45 marbles in total 12+11+17+5=45
And then 28 because you add all the marbles that are NOT blue 12+11+5=28
