Answer:
Step-by-step explanation:
f(3)=2*3^2 - 3*3^2 + 1
=2*9 - 3*9 + 1
=18-27+1
=19-27
=-8
First you multiply both sides by -4.
(y + 12) * (-4)
___________ = 5 (-4)
-4
then you should simplify.
y + 12 = -20
subtract 12 from both sides to isolate the y.
y + 12 - 12 = -20 -12
-20 minus 12 is -32.
y = -32.
