Determine the number of solutions to this system of linear equations: 2x+y=6 4x+2y=8 (1 point) Responses 0 0 infinite infinite 2 2 1

1 answer

To determine the number of solutions for the given system of equations:

  1. Identifying the equations: \[ \text{Equation 1: } 2x + y = 6 \] \[ \text{Equation 2: } 4x + 2y = 8 \]

  2. Simplifying the second equation: The second equation can be rewritten to see if it's a multiple of the first equation: \[ 4x + 2y = 8 \quad \text{(divide by 2)} \] \[ 2x + y = 4 \]

  3. Now we have two equations:

    • From the first equation: \( 2x + y = 6 \)
    • From the simplified second equation: \( 2x + y = 4 \)
  4. Comparing the two equations: The left-hand sides of both equations are the same (\(2x + y\)), but the right-hand sides are different: \[ 6 \neq 4 \] This indicates that the two equations are inconsistent.

  5. Conclusion: Since the two equations represent parallel lines that never intersect, the system has no solutions.

The number of solutions to the system of equations is 0.
