y = 11/21

To solve this first evaluate the power (then calculate the sum):

$4^{2}$ y - $3^{2}$ = 5y + (-5 + 7)

16y - 9 = -5y + 2

Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):

16y - 9 = -5y + 2

16y + 5y = 2 + 9

Next Collect the like terms and calculate the sum:

16y + 5y = 2 + 9

21y = 11

Lastly divide both sides of the equation by 21:

21y = 11

y = $\frac{11}{21}$

Answer:

Answer B

Step-by-step explanation:

Write out f(x) and g(x) in a column; we will subtract g(x) from f(x):

f(x) = x^2 - 9 or f(x) = x^2 - 9

-g(x) = -(2 - x) or -g(x) = +x -2

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

f(x) - g(x) = x^2 + x - 11 (Answer B)
