Answer:
x = 2
Step-by-step explanation:
3 • (x + 2) - 12 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
3x - 6 = 3 • (x - 2)
Equation at the end of step 3 :
3 • (x - 2) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2
One solution was found :
x = 2
