    SOLUTION

    GIVEN

    The point (3, 2) lies on the graph of the equation 5x + ay = 19

    TO DETERMINE

    • The value of a
    • Write the equation of the line

    EVALUATION

    Here the given equation of the line is

    5x + ay = 19

    Now the point (3,2) lies on the graph of the equation 5x + ay = 19

    Thus we get

    ( 5 × 3 ) + ( a × 2 ) = 19

    ⇒ 15 + 2a = 19

    ⇒ 2a = 4

    ⇒ a = 2

    Also the equation of the line is

    5x + 2y = 19

    FINAL ANSWER

    Hence the required value of a = 2
