Final Answer:
The answer of the given equation that "the system of equations" is d) All of the above
Step-by-step explanation:
You can solve the given system of equations using various methods:
a) Substitution method:Solve one of the equations for one variable and substitute it into the other equations.
b) Elimination method: Add or subtract equations to eliminate one variable, then solve the resulting system.
c) Matrix method: Represent the system as a matrix and use methods like Gaussian elimination or matrix inversion to find the solution.
All three methods (substitution, elimination, and matrix) are applicable to solving systems of linear equations, and you can use any of them to find the solution to the provided system.
Therefore, the correct answer is d) All of the above. The choice of method often depends on personal preference or the specific characteristics of the system being solved.
