    Question

    In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer if;

    I.√(3x-17)+ x=15 II.  y+

     135/y=24 
    A x < y Correct Answer Incorrect Answer
    B x > y Correct Answer Incorrect Answer
    C x=y or no relationship cannot be established between x and y Correct Answer Incorrect Answer
    D x ≥ y Correct Answer Incorrect Answer
    E x ≤ y Correct Answer Incorrect Answer

    Solution

    I.√(3x-17)+ x=15 √(3x-17)=15-x  On squaring both sides 3x-17=(15-x)²  3x-17=225+x²-30x  x^2+225-33x+17=0  x²-33x+242=0  x²-22x-11x+242=0  x(x-22)- 11(x-22)= 0  x=11,22  II.  y+  135/y=24  y²+135/y=24  y²+135=24y  y²-24y+135=0  y²-15y-9y+135=0  y=15,9  Hence, relationship cannot be established between x and y.
