    Answer:

    Find three different solution of the equation

    10x + 11y = 21

    ANSWER

    Given equation 10x+11y=21

    (i)10x+11y=21

    If y=1 put in equation we get

    10x+11×1=25

    ⇒10x+11=21

    ⇒10x=21−11=10

    ⇒x=1

    (1,1)

    (ii)10x+11y=21

    If y=2 put in equation we get

    10x+11×2=21

    ⇒10x+22=21

    ⇒10x=21−22=−1

    ⇒x= 10

    −1

    ,21

    (iii)10x+11y=21

    If y=3 put in equation we get

    10x+11×3=21

    ⇒10x+33=21

    ⇒10x=21−33=−12

    ⇒x=
