Answer:
x = 3
Explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-9 + 3x = 3 • (x - 3)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x-3 = 0
Add 3 to both sides of the equation :
x = 3
