Question

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

Answer 1

Hola Mate !!

Here's your answer :-

3(5z - 7) - 2(9z - 11) = 4(8z - 13) - 17
=> 15z - 21 - 18z + 22 = 32z - 52 - 17
=> 15z - 18z - 32z = - 52 - 17 + 21 - 22
=> - 35z = - 70
=> z = - 70/ - 35
=> z = 2

Answer 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
