    Question

    I.тИЪ(3x-17)+ x=15 II. ┬аy+

    ┬а135/y=24┬а In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer if;
    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 тЙе y Correct Answer Incorrect Answer
    E x тЙд y Correct Answer Incorrect Answer

    Solution

    I.тИЪ(3x-17)+ x=15 тИЪ(3x-17)=15-x┬а On squaring both sides 3x-17=(15-x)┬▓┬а 3x-17=225+x┬▓-30x┬а x^2+225-33x+17=0┬а x┬▓-33x+242=0┬а x┬▓-22x-11x+242=0┬а x(x-22)- 11(x-22)= 0┬а x=11,22┬а II. ┬аy+ ┬а135/y=24┬а y┬▓+135/y=24┬а y┬▓+135=24y┬а y┬▓-24y+135=0┬а y┬▓-15y-9y+135=0┬а y=15,9┬а Hence, relationship cannot be established between x and y.┬а
