Answer 3

To solve for "z" in the equation 15z - 12.5z = 21.4275, you can first combine like terms on the left side of the equation:

(15z - 12.5z) = 2.5z

Now the equation becomes:

2.5z = 21.4275

To isolate "z," you can divide both sides of the equation by 2.5:

2.5z / 2.5 = 21.4275 / 2.5

z = 8.57

So, the value of "z" is approximately 8.57.
