    Standard form : Ax + By = C

    x + y + 3 = - 2x + 4y + 18

    x + 2x + y - 4y = 18 - 3

    3x - 3y = 15

    Answer

    3x - 3y = 15

    Standard form of (ax + by = c) given equation is - 3x + 3y = 3

    Step-by-step explanation:

    Given equation: x + y + 3 = - 2x + 4y

    Standard form of equation: ax + by = c

    Solution:

    x + y + 3 = - 2x + 4y

    = - 2x + 4y = x + y + 3

    By subtracting x and y from both sides of equation:

    = - 2x - x + 4y - y = x + y + 3 - x - y

    = - 3x + 3y = 3

    So standard form of equation is - 3x + 3y = 3 in which - 3 is a and 3 is b and 3 is equal to c.
