6x - 9 = 2x +7 what is x

x = 4

Step-by-step explanation:

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

                    6*x-9-(2*x+7)=0

Pull out like factors :

  4x - 16  =   4 • (x - 4)

Solve :    4   =  0

Add  4  to both sides of the equation :

                     x = 4

Isolate the variable by dividing each side by factors that don't contain the variable.

Step-by-step explanation:

and your answer is  x=4

both equations and proportions are better.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
