(05.02) 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)
