    Find the value of y (Eliminate) :

    -2x + y = 1 × -4

    -4x + y = -1 × -2

    8x – 4y = -4

    8x 2y = 2 _

    – 2y = -6

    y = -6 ÷ (-2)

    y = 3

    Find the value of x (Substitute) :

    -2x + y = 1

    -2x + 3 = 1

    -2x = 1 – 3

    x = -2 ÷ (-2)

    x = 1

    The value of :

    x = 1

    y = 3

    Hope it helpful and useful :)
