All of the following expressions are equivalent except -4 - y -4 + y -y - 4 -y + (-4)

the answer is 11.2 (i know i’m late)

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
