Option D is correct.
Value of z =5
Step-by-step explanation:
Given the equation:
Using distributive property:
Apply distributive property in the given equation we have;
⇒
Subtract 4 from both sides we get;
6z + 4 -4 = 34-4
Simplify:
6z = 30
Divide by 6 to both sides of an equation, we get;
z = 5
Therefore, the value of z is, 5
