    Answer:

    x = -3

    Step-by-step explanation:

    Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                        5-4*x-(17)=0

    1.1     Pull out like factors :

      -12 – 4x  =   -4 • (x + 3)

    2.1      Solve :    -4   =  0

    This equation has no solution.

    A a non-zero constant never equals zero. 2.2      Solve  :    x+3 = 0

    Subtract  3  from both sides of the equation :

                         x = -3
