Question

9z-4=68 how to solve it ​

Answer 1

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,

=> $9z-4=68$

Now add both sides by $4$, we get

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

Simplifying it further, we get

=> $9z = 72$

Divide both sides by $9$, we get

=> $z = 8$

Hence, the required solution is 8.
