Formula Used in “Elimination Method Calculator”
The elimination method is an effective technique for solving systems of linear equations. The standard formula used in this method involves manipulating equations to eliminate one of the variables, allowing for easier solutions.
The elimination method can be represented in LaTeX-style notation as:
Ax + By = C
Dx + Ey = F
Step-by-Step Breakdown of the Formula
In the above equation, each variable is defined as follows:
- A: Coefficient of the first variable, x, in the first equation.
- B: Coefficient of the second variable, y, in the first equation.
- C: Constant term in the first equation.
- D: Coefficient of the first variable, x, in the second equation.
- E: Coefficient of the second variable, y, in the second equation.
- F: Constant term in the second equation.
Calculation Process
To apply the elimination method effectively, follow these steps:
- Arrange both equations in standard form (Ax + By = C).
- Multiply one or both equations by a suitable number to align coefficients of one variable.
- Add or subtract the equations to eliminate one variable.
- Solve the resulting equation for the remaining variable.
- Substitute back into one of the original equations to find the value of the eliminated variable.
Example Calculation
Let’s consider the following system of equations:
| Equation | Formulation |
|---|---|
| 1 | 2x + 3y = 8 |
| 2 | 4x – 3y = 2 |
Using the Elimination Method
We can eliminate y from the equations:
- First, add both equations to eliminate y:
- Resulting in:
- Solve for x: x = 10/6 = 5/3
- Substitute x = 5/3 into Equation 1:
- Solving gives:
Equation 1: 2x + 3y = 8
Equation 2: 4x – 3y = 2
Adding: (2x + 3y) + (4x – 3y) = 8 + 2
6x = 10
2(5/3) + 3y = 8
3y = 8 – 10/3 = 24/3 – 10/3 = 14/3, thus y = 14/9
Conclusion
The solution to the system of equations is:
| Variable | Value |
|---|---|
| x | 5/3 |
| y | 14/9 |
This example illustrated the practical application of the elimination method, showcasing its effectiveness in solving linear equations. For additional resources on linear equation solutions, visit Khan Academy.
