how many solutions does the system of equations have? 8x - 6y = 48

8x + 6y = 48

1 answer

To determine how many solutions the system of equations has, we can analyze the two equations:

  1. \( 8x - 6y = 48 \)
  2. \( 8x + 6y = 48 \)

We can solve this system by either substitution or elimination. Here, we'll use elimination.

First, let's rewrite both equations for clarity:

  • Equation 1: \( 8x - 6y = 48 \)
  • Equation 2: \( 8x + 6y = 48 \)

Now, we can subtract Equation 1 from Equation 2:

\[ (8x + 6y) - (8x - 6y) = 48 - 48 \]

This simplifies to: \[ 12y = 0 \]

Solving for \( y \) gives: \[ y = 0 \]

Now, we can substitute \( y = 0 \) back into either of the original equations to find \( x \). We'll use Equation 1:

\[ 8x - 6(0) = 48 \]

This simplifies to: \[ 8x = 48 \]

Dividing both sides by 8 gives: \[ x = 6 \]

So we have found a single solution: \( (x, y) = (6, 0) \).

To summarize, the system of equations has exactly one solution.
