solve this equation and tell whether the answer turns out to be a false equation or identity

4(z-1)=5z

1 answer

To solve the equation 4(z-1) = 5z, first distribute the 4 on the left side:

4z - 4 = 5z

Next, subtract 4z from both sides of the equation to isolate the variable z:

-4 = z

So, the solution to the equation is z = -4.

This equation is not an identity, it is a false equation because it has a specific value for z that makes the equation true (z = -4).
