1. Problem Description
The problem asks us to solve the given system of equations:
(1)
(2)
If there is no unique solution, we must state a reason.
2. Solution Steps
First, let's simplify the equations. We can divide the first equation by 2:
(1')
We can divide the second equation by -8:
(2')
Notice that equation (2') is exactly twice equation (1'). Let us check if equation (2) is a multiple of equation (1). If we multiply equation (1) by -8, we get:
Which is exactly equation (2). Therefore, the two equations are linearly dependent, meaning they represent the same line. This means there are infinitely many solutions.
We can express y in terms of x from equation (1'):
Any ordered pair of the form is a solution to the system.
3. Final Answer
B. There are infinitely many solutions.
