Solving Simple Equation in Algebra

**In this lesson, you’ll learn how to solve simple algebraic equations.**  

That means finding the value of the variable (like `x` or `y`) that makes the equation true.

### 🔹 **What is an Equation?**

An **equation** is like a balance. It has **two sides** and an **equal sign (=)** between them.

> **Example:**  

> `x + 3 = 7`

This means:  

"What number added to 3 gives 7?"

---

### 🔸 **Step-by-Step Method**

Let’s solve this:

**`x + 3 = 7`**

➡️ **Step 1:** Subtract 3 from both sides:

x + 3 − 3 = 7 − 3  

x = 4

✅ So the answer is: **x = 4**

---

### 🔸 **Example 2:**

**`y − 2 = 5`**

Add 2 to both sides:

y − 2 + 2 = 5 + 2  

y = 7

✅ So the answer is: **y = 7**

---

### 🔸 **Example 3:**

**`a ÷ 2 = 6`**

Multiply both sides by 2:

a ÷ 2 × 2 = 6 × 2  

a = 12

✅ So the answer is: **a = 12**

---

### ✨ **Important Rule to Remember:**

> **Whatever you do to one side of the equation,**  

> do the **same to the other side** to keep the balance!

---

### ✅ **Practice Questions:**

Solve the following equations:

1. `x + 5 = 10`  

2. `m − 4 = 3`  

3. `y ÷ 3 = 4`  

4. `a × 2 = 16`
