    \[x=3,\] \[y=4\] is a solution of the linear equation:

    A) \[2x+3y-17=0\]

    B) \[3x+2y-17=0\]

    C) \[2x-3y+17=0\]

    D) \[2x+3y+17=0\]

    Correct Answer: B

    Solution :

    [b]
    [a] \[LHS=2(3)+3(4)-17=1\ne RHS\]
    [b] \[LHS=3(3)+2(4)-17=0=RHS\]
    [c] \[LHS=2(3)-3(4)+17=11\ne RHS\]
    [d] \[LHS=2(3)+3(4)+17=35\ne RHS\]
    \[\therefore \,\,x=3,\,\,y=4\] is the solution of the equation \[3x+2y-17=0.\]
