x +4 = 9

Amanita, let's solve the equation $x + 4 = 9$ step by step. Here’s the plan:

Step-by-Step Plan:

1. Understand the Equation: We have $x + 4 = 9$. Our goal is to find the value of $x$ that makes this equation true.
2. Isolate $x$: To find $x$, we need to get it alone on one side of the equation. We do this by removing the $+4$ from the left side.
3. Use the Inverse Operation: The opposite (inverse) of adding 4 is subtracting 4. So, we subtract 4 from both sides of the equation to keep it balanced.
4. Write the New Equation: After subtracting, we simplify both sides to find the value of $x$.

Let’s execute each step:

Step 1: Start with the equation

Step 2: Subtract 4 from both sides

Step 3: Simplify both sides Now, let's calculate $9 - 4$ to find the value of $x$. Amanita, after subtracting 4 from both sides, we have:

So, the solution to the equation $x + 4 = 9$ is $x = 5$. This means if you put 5 in place of $x$, the equation will be true:

And that is correct!
