Question

-4*(3-5z)=18z-7Помогите!Заранее спасибо

Answer 1

-12+20z=18z-7
20z-18z=12-7
2z=5
z=2,5

Answer 2

-12+20z=18z-7
20z-18z= -7+12
2z=5
z=5:2
z=2,5

Answer 3

I can help you with your algebra problem. Here are the steps to solve it:

- Distribute the -4 to the terms inside the parentheses: -12 + 20z = 18z - 7 - Subtract 20z from both sides: -12 - 2z = -7 - Add 12 to both sides: -2z = 5 - Divide both sides by -2: z = -5/2

The solution is z = -5/2. You can check your answer by plugging it back into the original equation and simplifying. You should get a true statement.
