Hello everyone,

I hope you are all doing well. I have recently encountered a problem while working on a PHP program, and I was hoping someone here could help me out.

I am trying to find the missing digit x from a given expression. Unfortunately, I am not able to figure out how to solve this problem. Can someone please assist me with this?

Here is the expression: <?php echo "2x + 12 = 30"; ?>

As you can see, there is a missing digit represented by x in the equation. I need to find the correct value of x that satisfies the equation. I have tried various approaches, but none of them seem to work.

If anyone has any idea or suggestions on how to solve this problem, I would greatly appreciate your help. Thank you in advance for your assistance!

Best regards,

Hi [Your Name]!

I had a similar situation not long ago, and I can offer some guidance on solving your problem. To find the value of x in the given equation, you can follow these steps:

1. Start by subtracting 12 from both sides of the equation: 2x + 12 - 12 = 30 - 12. This simplifies to 2x = 18.

2. Next, divide both sides of the equation by 2: 2x/2 = 18/2. This gives us x = 9.

So, the missing digit in the expression 2x + 12 = 30 is 9. By substituting x with 9 in the equation, it should hold true.

I hope this helps you solve your problem! If you have any further questions, feel free to ask.
