    First Equation,

    10x + 15y = 20

    Second Equation,

    - 9x - 15y = - 21

    First Equation + Second Equation,

    10x + 15y - 9x - 15y = 20 - 21

    x = - 1

    Substituting value of x in First Equation,

    10 (-1) + 15y = 20

    -10 + 15y = 20

    15y = 30

    y = 2

    Hence, the solution is (-1, 2)
