Final answer:
To solve a four-variable system of equations, you can use methods like Cramer's Rule, Gaussian Elimination, Matrix Inversion, or Row-Reduced Echelon Form. Let's consider Cramer's Rule for this example and follow the steps to solve the system.
Step-by-step explanation:
When solving a system of four equations with four unknowns, there are several methods that can be used, including Cramer's Rule, Gaussian Elimination, Matrix Inversion, and Row-Reduced Echelon Form. Let's consider Cramer's Rule for this example.
- Write the system of equations in matrix form.
- Calculate the determinant of the coefficient matrix.
- Calculate the determinants of the matrices obtained by replacing each column of the coefficient matrix with the constant terms.
- Find the values of the unknowns by dividing the determinants found in step 3 by the determinant found in step 2.
These steps can be followed to solve a four-variable system of equations using Cramer's Rule.
