3(x-4)+5x=4x+4(x-3) is this conditional

The given equation is not the conditional equation.

Step-by-step explanation:

A conditional equation is true only certain values of the numbers present in it.

    for example  x + 3 = 9  is true only, if x = 6

                         3x - 5 = 10 is true only, if x = 5

The given equation is an Identity equation in which both sides of the equation is equal.    

                     3(x - 4) + 5x = 4x + 4(x - 3)

                     3x - 12 + 5x = 4x + 4x - 12

                                   8x  = 8x.
