To solve: the system by substitution and suggest whether the system has one solution, infinitely many solutions, or no solution. .
Answer to Problem 28P
The solution is
The system has one solution.
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
Therefore the solution is
