Question

Which of the following values of z satisfies 7 z − 4 = 38 ?

Answer 1

Hello buddy , The value that satisfies 7z-4=38 is 6.

Step-by-step explanation:

7z-4=38

7z=38+4

7z=42

z=42/7

z=6

Verification:

LHS=7z-4

=7(6)-4

=42-4

=38=RHS

Hence verified.

Hope you've understood !

Answer 2

Answer:

7z - 4 = 38

7z = 38 + 4

7z = 42

z = 43/7

Hence, z = 43/7
