    Answer:

    (2, 0 )

    Step-by-step explanation:

    Given the 2 equations

    5x – 2y = 10 → (1)

    x + 4y = 2 → (2)

    Multiplying (1) by 2 and adding to (2) will eliminate the y- term

    10x – 4y = 20 → (3)

    Add (2) and (3) term by term to eliminate y

    11x + 0 = 22

    11x = 22 ( divide both sides by 11 )

    x = 2

    Substitute x = 2 into either of the 2 equations and solve for y

    Substituting into (1)

    5(2) – 2y = 10

    10 – 2y = 10 ( subtract 10 from both sides )

    – 2y = 0, so

    y = 0

    solution is (2, 0 )
