Solve each system by substitution. Tell whether the system has one solution, infinitely many solutions, or no solution.
To solve: The system by substitution and suggest whether the system has one solution, infinitely many solutions, or no solution.
Answer to Problem 33P
Therefore the solution is
We have one solution, which is consistent and independent.
Explanation of Solution
Given information:
Calculation:
In order to solve two system by substitution, we solve one of the equations for one of
the variables, and plug this into other equation.
First we solve equation
Now we substitute
By plugging Y=-1 into
Therefore the solution is
We have one solution, which is consistent and independent.
