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
