Answer 1

Ответ:

20z-17,5z=8,9275

2.5z=8,9275

z=4.46375

Answer 2

Of course, I'll help you solve the equation. Let's simplify it step by step:

Given equation: 20z - 17.5z = 8.9275

First, combine the like terms on the left side of the equation: 20z - 17.5z = 2.5z

Now, the equation becomes: 2.5z = 8.9275

To solve for z, divide both sides of the equation by 2.5: z = 8.9275 / 2.5

Now, let's calculate the value of z: z = 3.571

So, the solution to the equation is z = 3.571. If you have any other questions or need further assistance, feel free to ask!
