Answer:

1)  y = -3x + 9

2) y = -3/4x + 6

3) y = x - 5

Step-by-step explanation:

1) 3x + y - 7 = 2

            +7   +7

        3x + y = 9

       -3x        -3x

                y = -3x + 9

2) 3x + 4y = 24

  -3x           -3x

          4y = -3x + 24

          4        4      4

          y = -3/4x + 6

3) x - y = 5

  -x        -x

      -y = -x + 5

       -1     -1   -1

        y = x - 5
