Mrac [35]

Answer:

Step-by-step explanation:

plug y into the first equation:

8x+5y=24

8x+5(-4x)=24

8x-20x=24

-12x=24

x=-24/12

x=-2

then plug x to the second equation

y=-4

y=-4(-2)

y=8

x=-2

y=8

N Squared - N = 90<br> N =?

mariarad [96]

N^2 - n = 90
n^2 - n - 90 = 0
(n - 10)(n + 9) = 0

n - 10 = 0
n = 10

n + 9 = 0
n = -9

answer is : n = 10 and n = -9
