Answer 1

1. 6p + 21 = 5
6p = 5-21
6p = -16
p = - 2 2/3
2. 2× - 9× = 8 + 6
-7× = 14
× = - 2
3. 30 = 3 (× + 2)
30 = 6× + 6
30 - 6 = 6×
24 = 6×
× = 4
4. 3× + 15 = 30
3× = 30 - 15
× = 15 / 3
× = 5

Answer 2

1.(2p+7)x3=5
    6p+21=5
          6p=5-21
            p=-16:5
            p=3,2
2.2x-9x=8+6
       -7x=14
          x=14:-7
          x=-2
