Question

Solve: 7z – 5 = 16
please answer step by step ​

Answer 1

z = 3

Step-by-step explanation:

7z - 5 = 16

=> 7z = 16 + 5

=> 7z = 21

=> z = 21 ÷ 7

=> z = 3

Hence the value of z is 3.

To verify :-

z = 3

7z - 5 = 16

=> (7×3) - 5 = 16

=> 21 - 5 = 16

=> 16 = 16

=> LHS = RHS

Hence verified.

hope it helps.

Answer 2

Answer:

Question :-

Solve: 7z – 5 = 16

Required Answer :-

z = 3

Solution :-

Let's find the value of z

$7z – 5 = 16$

$7z = 16 + 5$

$7z = 21$

$z = \frac{ 2\cancel1}{\cancel7}$

$z = 3$

Verification :-

We will verified our answer by substituting the value of z as 3

$7z – 5 = 16$

$7 \times 3 - 5 = 16$

$21 - 5 = 16$

$16 = 16$

$LHS = RHS$

Hence verified
