Question

please tell me answer​

Answer 1

Step-by-step explanation:

(b) (z-2)-9=30

z-2 = 30+9

z-2 = 39

z = 39+2

z = 41

Answer 2

Q9.

a) 7x - 25 = 94

   7x = 94 + 25

   7x = 119

    x = 119/7

    x = 17

b)  (z-2) - 9 = 30

    (z-2) = 30 + 9

    (z-2) = 39

    z-2 = 39

    z = 39 + 2

    z = 41

c)  6 added to a number p divided by 5 gives us 9 as the result.
