    To check whether the given linear equation 3x+6=15 is true for x=3, substitute x=3 in the qiven eqaution and check whether L.H.S=R.H.S
    For the given equation, 
    L.H.S = 3x+6
    Substitute x=3 in the given equation,
    Therefore, L.H.S = 3x(3)+6
    L.H.S = 9+6
    L.H.S = 15
    From the given equation, R.H.S = 15
    It is clear that, L.H.S = R.H.S for x=3.
    Therefore, the given linear equation 3x+6=15 is true for x=3.
