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 will replace 2x+4y=10 with is 7x+7y=12. Is Marla correct?
