3(5z-7)-2(9z-11)=4(8z-13)-17

15z-21-18z+22=32z-52-17

(-3z)+1 = 32z -69

35z = 70

so, z =2

Answer:

             z = 2

Explanation:

  Given simple equation:

                     3(5z-7)-2(9z-11)=4(8z-13)-17

                      => 15z-21-18z+22=32z-52-17

                      =>15z-18z-32z = -52-17+21-22

                    => (15-18-32)z = -69-1

                          => -35z = -70

                        => z = (-70)/(-35)

                         => z = 2

               Therefore,

                  z = 2
