To state: A matrix that represents the system then solve the system and tell the method used and why.
The resultant solution is
Given information:
The given system equations is:
Explanation:
Consider the given system:
Write the matrix representing the system:
Let’s number the equations,
Substitute the value of b in equation (1) and (2),
Now multiply equation (4) by 2,
Add equation (5) and (6) to eliminate variable c ,
Now find the value of variable c by substituting the value of a in equation (4) and simplify,
Therefore, the solution for the given system of equation is
The substitution method is best method to solve this system because it is easy to solve one variable in the given system.
