  1. Answer:

    (x , y) = (2 , 1)

    Step-by-step explanation:

    // Solve equation [1] for the variable x

    [1] x = -4y + 6

    // Plug this in for variable x in equation [2]

    [2] -(-4y+6) – 2y = -4

    [2] 2y = 2

    // Solve equation [2] for the variable y

    [2] 2y = 2

    [2] y = 1

    // By now we know this much :

    x = -4y+6

    y = 1

    // Use the y value to solve for x

    x = -4(1)+6 = 2
