Math Problem Statement
Solution
The given system of equations is:
To determine how many solutions this system has, we will analyze the equations by solving them.
Step 1: Multiply the second equation by 2.
This gives:
Step 2: Add this new equation to the first equation.
Simplifying:
This result indicates that the two equations are dependent, meaning they represent the same line. Therefore, there are infinitely many solutions to this system, as every point on the line satisfies both equations.
Conclusion:
The system has infinitely many solutions.
