Final answer:

Upon solving the given system of equations, the values of x and y were found to be x = 2.5 and y = 2, which does not match any of the provided options. There may be a typo or incorrect information given in the question.

Step-by-step explanation:

To solve the following system of equations:

  • 2x+3y = 11
  • 4x-2y=6

We will solve the simultaneous equations for x and y.

  1. First, we'll multiply the first equation by 2, so that we can eliminate y by adding it to the second equation:
    2*(2x+3y) = 2*11 which gives 4x+6y = 22.
  2. Adding the second original equation, 4x-2y=6, to the modified first equation, we get:
    (4x+6y) + (4x-2y) = 22+6, which simplifies to:
    8x+4y = 28.
  3. Now divide the resulting equation by 4, we get:
    2x+y = 7.
  4. Next, we'll subtract the first original equation from this result to solve for y:
    (2x+y) - (2x+3y) = 7-11, which simplifies to:
    -2y = -4...
  5. From the last result, we find that y = 2.
  6. Substituting y = 2 into the first original equation, 2x+3y = 11 gives us:
    2x + 3*(2) = 11,
    which simplifies to:
    2x + 6 = 11, and finally
    x = 2.5, which is not an option given.

It seems there has been a mistake because none of the provided options matches our calculations. The correct values of x and y should be rechecked. Please ensure there are no typos in the options provided or the system of equations.
