Example Question #72 : Solving Equations

Find the solution to the following equation.

Possible Answers:

Correct answer:

Explanation:

Find the solution to the following equation.

To find the solution of this equation, we need to find the value for x, which makes the given equation true.

We do this by working backwards and manipulating the equation.

The easiest first step would probably be to subtract 23 from both sides:

By doing so, we can simplify the equation to get:

Next, simply divide both sides by 9 to get the answer!

So we get:
