-х=53. - х=-9. |х|-2=1 3|х|+2=26

Answer 1

Ответ:)

Пошаговое объяснение: удачи!

-х=53.

х=-53

- х=-9.

х=9 ( минусы вылетают)

|х|-2=1

х-2=1

х=2+1

х=3

______ проверка:

3-2=1

1=1

3|х|+2=26

3х+2=26

3х=26-2

3х=24

х=24:3

х=8

________ проверка;

3|8|+2=26

  26=26

Answer 2

Let's solve each of these equations one by one:

1. -x = 53

To solve for x, simply multiply both sides of the equation by -1 to isolate x:

-x = 53 x = -53

2. -x = -9

Again, to solve for x, multiply both sides of the equation by -1:

-x = -9 x = 9

3. |x| - 2 = 13

To solve for x, isolate |x| on one side of the equation and then solve for x:

|x| - 2 = 13

First, add 2 to both sides:

|x| = 13 + 2 |x| = 15

Now, since |x| can be either positive or negative, we have two possible equations to solve:

1. x = 15
2. -x = 15

For the first equation, x = 15.

For the second equation, multiply both sides by -1:

-x = 15 x = -15

So, there are two solutions for this equation: x = 15 and x = -15.

4. 3|x| + 2 = 26

To solve for x, isolate |x| on one side of the equation and then solve for x:

3|x| + 2 = 26

First, subtract 2 from both sides:

3|x| = 26 - 2 3|x| = 24

Now, divide both sides by 3:

|x| = 24 / 3 |x| = 8

Again, since |x| can be either positive or negative, we have two possible equations to solve:

1. x = 8
2. -x = 8

For the first equation, x = 8.

For the second equation, multiply both sides by -1:

-x = 8 x = -8

So, there are two solutions for this equation: x = 8 and x = -8.
