2z + 1 = z

What value of z satisfies the equation above?

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
