I hope this helps you in any way.Have a great day :)
X=3y+5 → x-3y=5 ..(1)
x-4y=3 ..(2)
→The second <span>equation we must multiplication by (-1)
→x-3y=5
→-x+4y=-3
x's is lost..
4y-3y=5-3
y=2
x-3.2=5
x=5+6=11</span>

Seems like a trick question to me, I think what this question is asking is "If you roll a 3 on a die, what is the chance of getting tails on a coin." The answer would then be 1/2 (one over two) and the events are independent because rolling a 3 on a die doesn't affect the chances of getting tails on a coin.
I believe the answer is 9x ( 2 + 7) = +9 x 2) + (9 x 7)
