Answer:

Step-by-step explanation:

5. 3x + 5 = 2x + 3

    x + 5 = 3

x = 2

y = 2(2) + 3 = 4 + 3 = 7

(2, 7)

6. 2x + y = 4

   3x - y = 1

    5x = 5

      x = 1

    2 + y = 4

     y = 2

 (1, 2)

7. 1/3x + 2 = 1/6x + 4

  2/6x + 2 = 1/6x + 4

   1/6x + 2 = 4

   1/6x = 2

   x = 12

y = 1/3(12) + 2= 4 + 2 = 6

   (12, 6)
