Question

|х|=-15|-х|=28,6-а=-|-12|-у=+|-6,5|-х=-|+8,7|​

Answer 1

Пошаговое объяснение:

|х|=-15

такого не может быть, так как модуль всегда раскрывается неотрицательно.

|-х|=28,6

совокупность:

х=28,6

х=–28,6

-а=-|-12|

–а=–12

а=12

-у=|-6,5|

–у=6,5

у=–6,5

-х=-|8,7|

–х=–8,7

х=8,7

Answer 2

I see that you have provided a series of equations. Let's solve each equation one by one:

1. |х| = -15

The absolute value of x cannot be negative, so there is no solution for this equation.

2. |-х| = 28

The absolute value of any number is always non-negative. Therefore, there is no solution for this equation either.

3. 6 - a = -|-12|

The absolute value of -12 is 12. Substituting this value into the equation, we get:

6 - a = -12

To isolate "a," we can add 12 to both sides of the equation:

6 - a + 12 = -12 + 12 18 - a = 0

Next, subtract 18 from both sides:

18 - a - 18 = 0 - 18 -a = -18

To solve for "a," multiply both sides by -1:

-a * (-1) = -18 * (-1) a = 18

So, the solution for this equation is a = 18.

4. -у = +|-6.5|

The absolute value of 6.5 is 6.5. Substituting this value into the equation and removing the plus sign, we have:

-у = -6.5

To isolate "у," we multiply both sides by -1:

-у * (-1) = -6.5 * (-1) у = 6.5

Therefore, the solution for this equation is у = 6.5.

5. -х = -|+8.7|

The absolute value of +8.7 is 8.7. Substituting this value into the equation and removing the minus sign, we have:

-х = 8.7

To isolate "х," we multiply both sides by -1:

-х * (-1) = 8.7 * (-1) х = -8.7

Thus, the solution for this equation is х = -8.7.

In summary: a = 18 у = 6.5 х = -8.7
