Question

19 – 2(3x+8) — 2(x — 18) – 1

Answer 1

Пошаговое объяснение:

1.раскрываем скобки

19 -(6x + 16) - (2x - 36)

19 - 6x - 16 - 2x + 36 - 1

2.находим x

38 - 8x =0

-8x=-38

x=38/8

x= 4,75

Answer 2

To simplify the expression 19 - 2(3x + 8) - 2(x - 18) - 1, you can follow these steps:

1. Distribute the constants inside the parentheses: 19 - 23x - 28 - 2x + 218 - 1

2. Multiply the constants: 19 - 6x - 16 - 2x + 36 - 1

3. Combine like terms: (19 - 16 - 1) - 6x - 2x + 36

4. Combine the constants: (2) - 8x + 36

5. Combine like terms again: 2 - 8x + 36

6. Finally, combine the constants: 38 - 8x

So, the simplified expression is 38 - 8x.
