Answer:

1)    y =  -4 + 3x

2)    y = (5/2) - (x/2)

Step-by-step explanation:

1) 3x - y = 4

        -y = 4 - 3x

   -1 * -y = -1 * 4 - 3x * -1   ( multiply each term by -1)

          y =  -4 + 3x

2) x + 2y = 5

         2y = 5 - x

            y = (5-x)/2

            y = (5/2) - (x/2)

1. 3x - y = 4
-3x -y = 4
-y = 4 - 3x
y = -4 + 3x

2. x + 2y = 5
-x + 2y = 5
2y = 5 - x
— ——
2 = 2
5-x
y = ———
