depends what 'a' =
It can't be solved because the discriminant of the given quadratic equation is less than zero meaning it has no real roots.

Y=15/(2c+2x)
5x+y=-7 3x+y=15 8=D

15+b = 23 Subtract 15 from both sides b = 8
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
5x+y=-7 3x+y=15 8=D
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
(x-3)(x-5) = 0
x2 + 3x - 15 = 0 you need to use the quadratic equation... since you have x to the second degree you will get two answers... yours two answers are... x = 2.6533 and -5.6533
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
15 + n = 24 (subtract 15 from both sides) n = 9
