Asystem of linear equations is shown below.
2x + 4y = 10
3x – y = 8
marla is attempting to prove that by replacing 2x + 4y = 10 with a different equation it will sometimes produce a new system of equations with the same solution. marla plans on multiplying 2x + 4y = 10 by 2 and then adding the results to the equation 3x – y = 8 in order to create a new equation. marla claims that the new equation that she will replace2x + 4y = 10with is7x + 7y = 12. is marla correct?
