​

Answer 1

Answer:

z=8 for more referene see my post

Answer 2

Answer:

=> The value of z is 8.

Step-by-step explanation:

Given that:-

$9z - 4 = 68$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

=> $9z - 4 = 68$

Add both sides by $4$, we get

=> $9z - 4+4 = 68+4$

Simplifying it further, we get

=> $9z = 68+4$

Add the numbers,

=> $9z = 72$

Divide both sides by $9$,

=> $z = 8$

Hence, the required solution is 8.
