**Examples of solving multi-step equations using different methods**

Here are some examples of how to solve multi-step equations using different methods:

**Example 1:** Solve for x: 2x + 3 = 7

**Solution:**

Using the elimination method:

- Subtract 3 from both sides of the equation: 2x = 4
- Divide both sides of the equation by 2: x = 2

**Example 2:** Solve for y: y^2 – 4y + 4 = 0

**Solution:**

Using the factoring method:

- Factor the quadratic equation: (y – 2)^2 = 0
- Take the square root of both sides of the equation: y – 2 = 0
- Add 2 to both sides of the equation: y = 2

**Example 3:** Solve for z: z/(z + 1) = 1/2

**Solution:**

Using the substitution method:

- Multiply both sides of the equation by z + 1: z = z/2 + 1/2
- Subtract z/2 from both sides of the equation: 1/2z = 1/2
- Multiply both sides of the equation by 2: z = 1

**Conclusion**

Multi-step equation calculators are a valuable tool for students and professionals alike. They can help you save time and solve complex math problems with ease. By learning how to use a multi-step equation calculator effectively, you can equip yourself with the skills you need to succeed in a variety of fields.
