-(-2x-6y=-16)

2x+6y=16
4x-6y=-58

Y's cancel out, then add the rest

6x=-42

divide both sides by six

x=-7

plug x into any previous equation

2(-7)+6y=16

-14+6y=16

6y=30

y=5

TiliK225 [7]

Answer:  The required value of f(3) is 81.

Step-by-step explanation:  We are given the following function :
