What is the value of x in 5(2x - 7)=15x-10?

Step  1  :Equation at the end of step  1  : 5 • (2x - 7) - (15x - 10) = 0 Step  2  :Step  3  :Pulling out like terms :

 3.1     Pull out like factors :

   -5x - 25  =   -5 • (x + 5) 

Equation at the end of step  3  : -5 • (x + 5) = 0 Step  4  :Equations which are never true :

 4.1      Solve :    -5   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 4.2      Solve  :    x+5 = 0 

 Subtract  5  from both sides of the equation : 
                      x = -5 

One solution was found :                   x = -5
