Asystem of equations is shown below: x + 3y = 5 (equation 1) 7x β 8y = 6 (equation 2) a student wants to prove that if equation 2 is kept unchanged and equation 1 is replaced with the sum of equation 1 and a multiple of equation 2, the solution to the new system of equations is the same as the solution to the original system of equations. if equation 2 is multiplied by 1, which of the following steps should the student use for the proof? show that the solution to the system of equations 3x + y = 5 and 8x β7y = 6 is the same as the solution to the given system of equations show that the solution to the system of equations 8x β 5y = 11 and 7x β 8y = 6 is the same as the solution to the given system of equations show that the solution to the system of equations 15x + 13y = 17 and 7x β 8y = 6 is the same as the solution to the given system of equations show that the solution to the system of equations β13x + 15y = 17 and 7x β 8y = 6 is the same as the solution to the given system of equations
