Question

432+(8×Х)=800-312,19+а=35-8,47-а=25+6,с-18=67-45,25-х=7+6

Answer 1

Пошаговое объяснение:

432 + ( 8 · х ) = 800 - 312

432 + ( 8 · х ) = 488

8 · х = 488 - 432

8 · х = 56

х = 56 : 8

х = 7

 

19 + а  = 35 - 8

19 + а = 27

а = 27 - 19

а = 8

47 - а = 25 + 6

47 - а = 31

а = 47 - 31

а = 16

с - 18 = 67 - 45

с - 18 = 22

с = 22 + 18

с = 40

25 - х = 7 + 6

25 - х = 13

х = 25 - 13

х = 12

Answer 2

Let's solve each equation step by step:

1. 432 + (8 × Х) = 800 - 312 To solve for X, we need to isolate it on one side of the equation. Let's simplify the right side first: 800 - 312 = 488

   Now, the equation becomes: 432 + (8 × Х) = 488

   Next, we'll subtract 432 from both sides: (8 × Х) = 488 - 432 (8 × Х) = 56

   Finally, divide both sides by 8: Х = 56 / 8 Х = 7

   Therefore, the value of X is 7.

2. а + 35 - 8,47 = 25 + 6 Let's simplify the left side of the equation first: а + 35 - 8.47 = 25 + 6 а + 26.53 = 31

   Now, subtract 26.53 from both sides: а = 31 - 26.53 а = 4.47

   Therefore, the value of а is 4.47.

3. 47 - а = 25 + 6 Let's simplify the equation: 47 - а = 31

   Now, subtract 47 from both sides: -а = 31 - 47 -а = -16

   Finally, multiply both sides by -1 to isolate а: а = -16 × -1 а = 16

   Therefore, the value of а is 16.

4. с - 18 = 67 - 45 Let's simplify the equation: с - 18 = 22

   Now, add 18 to both sides: с = 22 + 18 с = 40

   Therefore, the value of с is 40.

5. 25 - х = 7 + 6 Let's simplify the equation: 25 - х = 13

   Now, subtract 25 from both sides: -х = 13 - 25 -х = -12

   Finally, multiply both sides by -1 to isolate х: х = -12 × -1 х = 12

   Therefore, the value of х is 12.

To summarize, the solutions to the equations are: X = 7, а = 4.47, а = 16, с = 40, х = 12.
