Answer:

x = 3

Step-by-step explanation:

Multiply the first equation by -1, then add it to second equation.

2x+9y = -12

-2x-7y = 8

-------------------

2y = -4

Solve for y

2y = -4

y = -2

Plug value of y into one of the equations and solve for x

2x + 9(-2) = -12

2x = 6

x = 3

Step-by-step explanation:

Step 1: Define

Identify

F(x) = x² - 15

G(x) = 4 - x

Step 2: Find

Substitute in functions: $\displaystyle \bigg( \frac{F}{G} \bigg)(x) = \frac{x^2 - 15}{4 - x}$

Step 3: Evaluate

Substitute in x [Function (F/G)(x)]: $\displaystyle \bigg( \frac{F}{G} \bigg)(-7) = \frac{(-7)^2 - 15}{4 - (-7)}$
Exponents: $\displaystyle \bigg( \frac{F}{G} \bigg)(-7) = \frac{49 - 15}{4 - (-7)}$
Subtract: $\displaystyle \bigg( \frac{F}{G} \bigg)(-7) = \frac{34}{11}$
