a)
To find: the graphs at the different steps.
a)
Answer to Problem 5PS
The solution is
Explanation of Solution
Given:
The given equation is
Calculation:
Consider the following system of linear equations
The two equations
Multiply equation (1) by -5 and add the resultant to the equation (2) to get
Put
Thus the solution is
The equation of the line at each step of the elimination process is the same.
b)
To find: the graphs at the different steps.
b)
Answer to Problem 5PS
The two equations
Explanation of Solution
Given:
The given equation is
Calculation:
Consider the following system of linear equations
The two equations
Multiply equation (3) by -2 to get
Note that this is same as the equation (4) also the graph of both the equations coincide.
Thus, the two equations
Hence the system of equations has infinite number of solutions.
