HEL A student wants to prove that she can solve a system of equations by replacing one of the equations with two times that equation and adding the other equation. The original system was 12x + 2y = 30
and 10x + y = 26. The student claims that her first step is to add the two linear equations. Select the option that refutes the student's claim
Adding the two equations is the same as multiplying the second equation by two
А
Adding the two equations is not the same as multiplying one of the equations by two then adding the equations
с
Adding the two equations is the fastest way to solve the system of equations
D
Adding the two equations cancels out both variables
