Answer 2

Answer:

=> The value of x is 3.

Step-by-step explanation:

Given that:-

$7z -5 = 16$

To find:- The value of the expression,

To find the value of x, we must apply the transposition method:

As we have,

=> $7z -5 = 16$

Add both sides by $5$, we get

=> $7z -5+5 = 16+5$

Simplifying it further, we get

=> $7z = 16+5$

Addin the numbers, we get

=> $7z = 21$

Divide both sides by $7$, we get

=> $z = 3$

Hence, the required solution is 3.
