Let’s solve the math problem shown on the card you’re holding.

The equation is:

x - 6 = 14

We need to find what number x is.

Step-by-step thinking:

Think of it like this:
You have a mystery number (that’s x), and when you take away 6 from it, you get 14.

So, to find the original number, you just add 6 back to 14.

Why? Because if subtracting 6 gives you 14, then adding 6 undoes that — and gets you back to the start.

So:

x = 14 + 6

Now do the addition:

14 + 6 = 20

So, x = 20

Let’s check our answer to be sure:

Plug x = 20 back into the original equation:

20 - 6 = 14 → Yes! That’s correct.
