Answer 1

Ответ:

17.42

Пошаговое объяснение:

-х+4.18=-5.12-7.5

-х+4.18=-12.62

-х=-12.62-4.8

-х=-17.42

х=17.42

Answer 2

Ответ:

х-4,18=7,5-(-5,12)

х-4,18=12,62

х=12,62+4,18

х=16,8

Answer 3

To solve the equation $7.5 - (x - 4.18) = -5.12$, follow these steps:

1. Distribute the negative sign inside the parentheses:

$7.5 - x + 4.18 = -5.12$

2. Combine like terms on the left side:

$11.68 - x = -5.12$

3. To isolate $x$, subtract 11.68 from both sides:

$-x = -16.8$

4. Finally, divide both sides by -1 to solve for $x$:

$x = 16.8$

So, the solution to the equation is $x = 16.8$.
