kolezko [41]

if it is solution point (4, –2) must satisfy both equations
(1) –3x – 2y = –8-->-3*4-2*(-2)=-8
-12+4=-8 then-->-8=-8 ok
(2) y = 2x – 5
-2=2*4-5=3---------->-2 is not 3

the point (4, –2) is not solution of the system of equations

p(10) = 2(10) +8 = 20 +8

p(10) = 28

The function definition tells you this (28) is the price of streaming 10 movies in a month.
