To find: the solution of the system.
Answer to Problem 38RE
The system has no solution
Explanation of Solution
Given:
Calculation:
Let's begin by labeling our three equations.
First use Operation
This simplifies to
Our new system, with the new Equation
Now, make substitutions to solve for
It seems that the solution to the system is found. Let's check the solution
This is a false equation, since
All three of the original equations are simply lines (they have only
Note that Equation
Conclusion: Therefore, the system has no solution
