PLEASE HELP ME easy algebra

(6,1)

Step-by-step explanation:

using substitution we find x=y+5, then we plug into the equation and find y and then using y we can find x

hope it helps!

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
