    What is the capital of Egypt? ( Cairo )

    1 Answer

    1. Quizzma Team

      Let’s analyze the system of equations step by step:

      1. Equations Given:

      – ( y = 2x + 6 )

      – ( 2y = 4x – 2 )

      We can simplify the second equation by dividing all terms by 2, giving us:

      – ( y = 2x – 1 )

      2. Finding Intersection Points:

      To find the solution set, we can set the two equations for (y) equal to each other:

      ( 2x + 6 = 2x – 1 )

      3. Solving the equation:

      Subtract (2x) from both sides:

      ( 6 = -1 )

      This leads us to a contradiction, which indicates that there is no solution to the system.

      Now, let’s fill in the statements for each student:

      Shannon

      Shannon correctly graphs the two lines and sees that they are parallel. This means the system has no solution.

      David

      David correctly sees that (y) cannot be equal to both 6 more than twice a number and 1 less than twice a number at the same time.

      Alex

      Alex correctly concludes that because (2x + 6) and (2x – 1) will never be equal, the system has no solution.
