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)

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
