Answer:
is the solution to the equation: 
The statement is true.
Option A is correct.
Step-by-step explanation:
We need to determine if
is the solution to the equation: 
Solving the equation first to find value of x

Combining like terms:

Subtracting 2x on both sides

Now, subtracting 12 on both sides

Divide both sides by -6

So, we get
Therefore we can say that
is the solution to the equation: 
The statement is true.
Option A is correct.
