STEP 1 : Equation at the end of step 1

(4 +  3 • (x - 7)) -  (3 - x)  = 0

STEP 2 : Pulling out like terms 3.1  

 Pull out like factors : 4x - 20  =   4 • (x - 5) Equation at the end of step 3 : 4 • (x - 5)  = 0

STEP 3 : Equations which are never true 4.1

  Solve :    4   =  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

Add  5  to both sides of the equation : x = 5

Answer:   x=5
