7x=7
x=1
1+3y= -8
y= -3
15=15
-8=-8
your final answer would be (x,y) = (1,-3)
Your answer is D. a = 2, b = -3, c = -27.
This is because to use the quadratic formula, your equation needs to equal 0, and to do that, you need to subtract 27 and 3x from the right to get 2x² - 3x - 27 = 0, and since the -3 is the x value, we use it for b.
I hope this helps!
