Question

(X+8)+12=25 (X+8)-12=25 (x-8)+12=25

Answer 1

Ответ:

Пошаговое объяснение:

х + 8 + 12 = 25

х + 20 = 25

х = 25 - 20

х = 5

х + 8 - 12 = 25

х - 4 = 25

х = 25 + 4

х = 29

х - 8 + 12 = 25

х + 4 = 25

х = 25 - 4

х = 21

Answer 2

Ответ:

X+8=13. x+8=37. x-8=13

x=5. x=29. x=21

Answer 3

To solve each of these equations, we'll isolate the variable $x$. Let's go through each one step by step:

1. $(x+8) + 12 = 25$

   First, simplify the left side:

   $x + 20 = 25$

   Next, isolate $x$:

   $x = 5$

   So, the solution is $x = 5$.

2. $(x+8) - 12 = 25$

   Again, simplify the left side:

   $x - 4 = 25$

   Isolate $x$:

   $x = 29$

   The solution is $x = 29$.

3. $(x-8) + 12 = 25$

   Simplify the left side:

   $x + 4 = 25$

   Isolate $x$:

   $x = 21$

   The solution is $x = 21$.

So, the solutions for the equations are:

1. $x = 5$
2. $x = 29$
3. $x = 21$
