6-9x = 7x - 10x - 30
The value of x is

X=6

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

                    6-9*x-(7*x-10*x-30)=0  

Pulling out like terms

1.1     Pull out like factors :

  36 - 6x  =   -6 • (x - 6)  

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-6 = 0  

Add  6  to both sides of the equation :  

                     x = 6
