(05.02) a system of equations is shown below: 5x + 2y = 3 (equation 1) 2x β 3y = 1 (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? (4 points) select one: a. show that the solution to the system of equations 7x β y = 4 and 2x β 3y = 1 is the same as the solution to the given system of equations b. show that the solution to the system of equations 2x + 5y = 3 and 3x β 2y = 1 is the same as the solution to the given system of equations c. show that the solution to the system of equations 9x + 4y = 5 and 7x β y = 4 is the same as the solution to the given system of equations d. show that the solution to the system of equations β4x + 9y = 5 and 2x β 3y = 1 is the same as the solution to the given system of equations
