• Quadratic formula

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:

1. Subtract 3 from both sides of the equation: 2x = 4
2. 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:

1. Factor the quadratic equation: (y – 2)^2 = 0
2. Take the square root of both sides of the equation: y – 2 = 0
3. 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:

1. Multiply both sides of the equation by z + 1: z = z/2 + 1/2
2. Subtract z/2 from both sides of the equation: 1/2z = 1/2
3. 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.
