Answer 1

Ответ:

Пошаговое объяснение:

1) (х+4)+12=23

х+4+12=23

х=23-4-12

х=7

2) 235+(х-47)=324

235+х-47=324

х=324-235+47

х=136

3) (23-х)+5=13

23-х+5=13

-х=13-23-5

х=15

4) 46+(3-х)=48

46+3-х=48

-х=48-46-3

х=1

5) 24-(х+2)=13

24-х-2=13

-х=13-24+2

х=9

Answer 2

Let's solve the equations one by one:

1. (x + 4) + 12 = 23

To solve this equation, we'll start by simplifying the left side:

x + 4 + 12 = 23 x + 16 = 23

Next, we'll isolate the variable x by subtracting 16 from both sides:

x + 16 - 16 = 23 - 16 x = 7

Therefore, the solution to this equation is x = 7.

2. 235 + (x - 47) = 324

Let's simplify the equation:

235 + x - 47 = 324

Combine like terms:

x + 188 = 324

Now, isolate the variable x by subtracting 188 from both sides:

x + 188 - 188 = 324 - 188 x = 136

The solution to this equation is x = 136.

3. (23 - x) + 5 = 13

Simplify the equation:

23 - x + 5 = 13

Combine like terms:

• x + 28 = 13

Subtract 28 from both sides:

• x + 28 - 28 = 13 - 28
• x = -15

So, the solution to this equation is x = -15.

4. 46 + (3 - x) = 48

Simplify the equation:

46 + 3 - x = 48

Combine like terms:

49 - x = 48

Subtract 49 from both sides:

49 - x - 49 = 48 - 49

• x = -1

The solution to this equation is x = 1.

5. 24 - (x + 2) = 13

Simplify the equation:

24 - x - 2 = 13

Combine like terms:

22 - x = 13

Subtract 22 from both sides:

22 - x - 22 = 13 - 22

• x = -9

The solution to this equation is x = 9.

To summarize, the solutions to the given equations are:

1. x = 7
2. x = 136
3. x = -15
4. x = 1
5. x = 9
