Math Problem Statement
What is the solution to the system of equations {-8x + 4y = -2, 4x - 2y = 1}?
Solution
To solve the given system of equations:
-8x + 4y = -2 \\ 4x - 2y = 1 \end{cases}$$ ### Step 1: Simplify the equations Both equations have common factors. Let's simplify each equation: 1. Divide the first equation by $$-2$$: $$-8x + 4y = -2 \quad \Rightarrow \quad 4x - 2y = 1$$ 2. The second equation is already $$4x - 2y = 1$$. ### Step 2: Analyze the simplified system After simplifying, the system becomes: $$\begin{cases} 4x - 2y = 1 \\ 4x - 2y = 1 \end{cases}$$ Both equations are identical, which means they represent the same line. ### Step 3: Determine the solution Since the two equations are the same, there are **infinitely many solutions**. Any point on the line $$4x - 2y = 1$$ satisfies the system. ### Final Answer: $$\text{inf.}$$ --- Do you want further details or examples on solving systems of equations?
