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

(−1, −10)
(1, −10)
(−1, 10)
(1, 10)

Option 2 ( 1,-10)

Step-by-step explanation:

The two equations are y = -x²-5x-4 (1)

                              and y = -x²+9x-18(2)

To get the solution of these lines we will substitute the value of y form equation 1 to 2.

- x² - 5x -4 = -x²+9x-18

Now by collecting similar terms on each side.

-x² -5x + x²-9x = -18 + 4

-14x = -14

14x = 14

x = 1

By putting the value of x in equation 1.

y = -1 - 5 - 4 = -10

So the solution is (1, -10)

Therefore Option 2 is the correct answer.
