I'm pretty sure It'd be 74° <3
If you are trying to eliminate the y, then both of the numbers in front of the y have to be the same, but one needs to be negative and the other positive.
The easiest way to do this is multiply the top equation by 3, so you'd get -6y for the top and you could cancel it out with the +6y on the bottom.
D. Multiply the top equation by 3.

Answer: 
Step-by-step explanation:
We know that the standard quadratic equation is ax^2+bx+c=0
Let's compare all the given equation to it and , find discriminant.
1. a=2, b= -7, c=-9
So it has 2 real number solutions.
2. a=1, b=-4, c=4

So it has only 1 real number solution.
3. a=4, b=-3, c=-1

So it has 2 real number solutions.
4. a=1, b=-2, c=-8
So it has 2 real number solutions.
5. a=3, b=5, c=3

Thus it does not has real solutions.
