To calculate: The solution set of system of equations,
Answer to Problem 17PPS
The system of equations has no solution.
Explanation of Solution
Given information:
The system of equations is provided below,
Formula used:
A system of equations with three variables can be solved by elimination method and substitution method. Select any two pairs of equations from the system and eliminate the same variable by adding or subtracting and then simplify it.
A system of equations is said to have no solution if all the equations have no points in common to each other in all the three planes.
Calculation:
Consider the provided system of equations as,
Recall that a system of equations with three variables can be solved by elimination method and substitution method. Select any two pairs of equations from the system and eliminate the same variable by adding or subtracting and then simplify it.
Multiply first equation by 2 and then add resulting equation and the second equation in order to eliminate y .
Add this equation and second equation to eliminate y as,
Now, multiply first equation by
Add this equation and the third equation to eliminate y as,
Multiply
Adding both the equations, result is,
Since, this equation
Recall that a system of equations is said to have no solution if all the equations have no points in common to each other in all the three planes.
So, the given system of equations has no point in common and hence, has no solution.
Thus, the system of equations has no solution.
