2x-4y = -3 2x = -3 + 4y x = -3/2 + 2y 2x-4y = -3 -4y = -2x -3 y = -2x/-4 -3/-4 y = 1/2x +3/4 This is the right answer
2x-4y = -3 2x = -3 + 4y x = -3/2 + 2y 2x-4y = -3 -4y = -2x -3 y = -2x/-4 -3/-4 y = 1/2x +3/4
disregard that answer above. I didn't see the negative 3
2x-4y = 3 2x = 3 + 4y x = 3/2 + 2y 2x-4y = 3 -4y = -2x +3 y = -2x/-4 +3/-4 y = 1/2x -3/4
