The answer is 41, because I just took the quiz and that was the correct answer :)
Answer:
You would have $18
Step-by-step explanation:
Have a good day!
From y-2x+3=0 we have y=2x-3
So we can replace y by 2x-3 in the equation: 9x+2y=5
And we have 9x+2(2x-3)=5
Or 9x+4x-6=5
and 13x=5+6
Or x=11/13, then y=2x-3= 2. 11/13-3=22/13-3= -17/13
So we have the answer <span>{(11/13, -17/13)}</span>
