Question

What is the solution to the following system of equations?
y = -x2 - 5x - 4
y = -x2 + 9x - 18

Answer 1

is it -2x or -x^2

Answer 2

-x^2

Answer 3

-x^2-5x-4=-x^2+9x-18

Can you solve that?

Answer 4

im not sure haha could you help me

Answer 5

\[-x^2 -5x-4=-x^2 +9x-18\]

first add x^2 to both sides (-5x-4=9x-18)
Then add 5x to both sides (-4=14x-18)
Then add 18 to both sides (14=14x)
Then divide 14x from both sides (x=1)
Now subsitute x in the equation and see what y equals
