    x = 2, y = 0

    Step-by-step explanation:

    Given the 2 equations

    2x + 5y = 4 → (1)

    3x - 5y = 6 → (2)

    Adding the 2 equations term by term will eliminate the term in y

    (2x + 3x) + (5y - 5y) = (4 + 6), that is

    5x = 10 (divide both sides by 5)

    x = 2

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

    Substituting in (1)

    2 (2) + 5y = 4

    4 + 5y = 4 (subtract 4 from both sides)

    5y = 0 ⇒ y = 0
