Answer:
Step-by-step explanation:Step 1 :
Equation at the end of step 1 :
2 • (x - 4) - 12 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
2x - 20 = 2 • (x - 10)
Equation at the end of step 3 :
2 • (x - 10) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
One solution was found :
x = 10
