Answer:
z = -1
Step-by-step explanation:
2z + 1 = z .
To get the value of z that satisfies the equation, what we simply do is to rearrange the equation by moving the coefficients. Now, we move z to the left hand side of the equation and 1 to the right side of the equation.
We should note that their signs will change afterwards.
2z - z = -1
z = -1
