Introduction
Simultaneous equations are a core part of algebra that students often encounter in mathematics. These equations involve two or more variables, and the objective is to find the values of these variables that satisfy all equations simultaneously. Solving simultaneous equations is essential for understanding algebra and advancing to more complex topics in mathematics. One of the best resources available to help students grasp this concept is Maths Genie, an online platform that offers a wide range of tutorials and exercises. In this blog post, we will explore how Maths Genie can help you solve simultaneous equations effectively, using step-by-step methods that are easy to follow.
What Are Simultaneous Equations?
Before diving into how maths genie helps with simultaneous equations, it’s crucial to understand what these equations are. Simultaneous equations consist of two or more equations with the same set of unknowns. These equations are solved together, meaning you find the values of the unknowns that satisfy all equations at the same time.
For example, consider the following two equations:
- 3x+2y=123x + 2y = 12
- 2x−y=42x – y = 4
Here, xx and yy are the unknowns, and your task is to find the values of xx and yy that satisfy both equations simultaneously. Maths Genie provides clear tutorials and examples to help you understand these concepts, which makes it an invaluable tool for learning.
Types of Simultaneous Equations
Simultaneous equations can be solved in various ways, and Maths Genie provides resources for all methods. The most common methods for solving simultaneous equations include:
1. Substitution Method:
The substitution method involves solving one of the equations for one variable, and then substituting that expression into the other equation.
2. Elimination Method:
The elimination method aims to eliminate one of the variables by adding or subtracting the equations.
3. Graphical Method:
In this method, you graph both equations and find the point where the two lines intersect. This point is the solution to the simultaneous equations.
Maths Genie offers explanations for each method, along with examples and practice problems that make learning these techniques simple and efficient.

Step-by-Step Guide to Solving Simultaneous Equations
Let’s walk through a step-by-step example of how to solve simultaneous equations using the substitution method, with the help of Maths Genie:
Step 1: Write the Equations
Consider the following system of equations:
3x+2y=123x + 2y = 12 2x−y=42x – y = 4
Step 2: Solve One Equation for One Variable
In this case, let’s solve the second equation for yy. We get:
y=2x−4y = 2x – 4
Step 3: Substitute Into the Other Equation
Now, substitute the expression for yy into the first equation:
3x+2(2x−4)=123x + 2(2x – 4) = 12
Step 4: Simplify and Solve for xx
Simplifying this equation:
3x+4x−8=123x + 4x – 8 = 12 7x−8=127x – 8 = 12 7x=207x = 20 x=207x = \frac{20}{7}
Step 5: Solve for yy
Substitute x=207x = \frac{20}{7} into the equation y=2x−4y = 2x – 4:
y=2(207)−4=407−287=127y = 2\left(\frac{20}{7}\right) – 4 = \frac{40}{7} – \frac{28}{7} = \frac{12}{7}
Thus, the solution to the system of equations is:
x=207,y=127x = \frac{20}{7}, \quad y = \frac{12}{7}
By following these steps, you can solve any pair of simultaneous equations. Maths Genie provides many more examples like this, helping you build your problem-solving skills and confidence.
