Answer 2

Answer:

z = 3 , n = 9/4 , p = 12/7 , x = 19/18

Explanation:

1) 5z - 6 = 12 - z

5z + z = 12 + 6

6z = 18

z. = 3

2) n/3 +1 = 4 - n

n/3 + n = 4 - 1

4n/3 = 3

4n = 9

n = 9/4

3) 5p + 7 = 19 - 2p

5p + 2p = 19 - 7

7p = 12

p = 12/7

4) 2x - 5/2 = 2/3 - x

2x + x = 2/3 + 5/2

3x = 19/6

x. = 19/18
