1(6x - 9) = (4x - 6)
ruslelena [56]

1(6x-9)=(4x-6)  

One solution was found :

                  x = 3/2 = 1.500

Rearrange:

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

                    1*(6*x-9)-((4*x-6))=0  

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

2.1     Pull out like factors :

  6x - 9  =   3 • (2x - 3)  

Equation at the end of step  2  :

 3 • (2x - 3) -  (4x - 6)  = 0  

Step  3  :

Equation at the end of step  3  :

 2x - 3  = 0  

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    2x-3 = 0  

Add  3  to both sides of the equation :  

                     2x = 3

Divide both sides of the equation by 2:

                    x = 3/2 = 1.500

One solution was found :

                  x = 3/2 = 1.500

kow [346]

Answer:

  C.  7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

  distance = speed × time

  300t = 350(t -1)

  300t = 350t -350 . . . . eliminate parentheses

  350 = 50t . . . . . . . . . . add 350-300t

  7 = t . . . . . . divide by 50

The trip out took 7 hours.
