Which of the following shows two equations that have the same solution? A.2x + y = 7 y = 2x + 7 B.x − 2y = 13 2y − x = 13 C.x + 3y = 14 x − 14 = -3y D.2x + 2y = 12 2x − 2y = -12
C because if you put both of the equations in standard form, they end up being the same equation. Change the second equation x - 14 = -3y x = -3y +14 add 14 to both sides x + 3y = 14 add 3y to both sides Then it matches the first equation, so they have the same solution.
