Some steps in solving an equation are more efficient than others. Complete parts (a) though (d) to determine the most efficient first step to solve the equation 34-5x=-21

Respuesta :

Answer:

The solution of the given equation   x =11

Step-by-step explanation:

Given equation 34 - 5x = -21

Step :-(a)

               Given equation 34 - 5x = -21

                              Subtracting '34' on both sides , we get

                                         34 - 5x -34 = -21 -34

Step:-(b)

                             on simplification , we get

                                          -5x = -55

Step:-(c)  

                           Dividing ' -5' on both sides , we get

                                             [tex]\frac{-5x}{-5} =\frac{-55}{-5}[/tex]

                        Cancellation '-5' on both sides , we get

                                               x = 11

Step :-(d)

                   The solution of the given equation   x =11
