  1. Answer:

    a)

    x=4, y=-2

    b)

    x=2, y=2

    c)

    x=0, y=0

    d)

    x=1, y=1

    e)

    x=3, y=3

    f)

    x=4, y=4

    Step-by-step explanation:

    a) (x,-2) = (4,y)

    x=4

    y=-2

    b) (3x, 4) = (6, 2y)

    3x=6 => x=2

    2y=4 => y=2

    c) (2x-1, y + 2) = (-1,2)

    2x-1 =-1 => x=0

    y+2 = 2 => y=0

    d) (2x + 4, y + 5) = (3x + 3,6)

    2x+4 = 3x+3 => x=1

    y+5 = 6 => y=1

    e) (x + y,y + 3) = (6, 2y)

    x+y = 6 => x+3 = 6 => x=3

    y+3 = 2y => y=3

    f) (x + y, x – y) – (8,0)​

    x+y = 8 => 2x=8 => x=4

    x-y = 0 => x=y => y=4
