I need to identify each equation as being an identity, contradiction, or conditional equation. I need to verify my solution. Here is my problem:

Rearranging to collect x terms and numbers will yield

Subtract 3x from both sides of equation to get x terms on right side

Subtract 9 from both sides to get a number on left side and isolate x term

Divide 3 to both sides of equation

Let's verify the solution by substituting x=-4/3 into simplified equation below

given as or simplifying

}

Now check to see if left side = right side. If it is then it's an identity.

So this is an identity and we can say that the solution is

I hope the above steps were helpful.
