Question

A system of equations is shown below:

x + 3y = 5 (equation 1)
7x - 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? (4 points)

Show that the solution to the system of equations 3x + y = 5 and 8x -7y = 6 is the same as the solution to the given syste
