Question

38 + x = 72x-31 = 45x 4= 206.y = 18b:7 = 536: c= 9​

Answer 1

Пошаговое объяснение:

38 + x = 72

х=72-38

х=34

x-31 = 45

х=45+31

х= 76

x×4= 20

х= 20÷4

х=5

6×y = 18

у= 18÷6

у= 3

b:7 = 5

b= 5×7

b= 35

36: c= 9

c= 36:9

c= 4

Answer 3

It seems like you've provided a set of equations and expressions. Let's solve them one by one:

1. 38 + x = 72 To solve for 'x' in this equation, simply subtract 38 from both sides: x = 72 - 38 x = 34

2. 72x - 31 = 45x To solve for 'x' in this equation, first, move all terms with 'x' to one side by subtracting 45x from both sides: 72x - 45x - 31 = 0 27x - 31 = 0 Now, add 31 to both sides to isolate 'x': 27x = 31 Finally, divide by 27 to find the value of 'x': x = 31 / 27

3. 4 = 206y To solve for 'y' in this equation, divide both sides by 206: y = 4 / 206 y = 2 / 103

4. 18b:7 = 536 To solve for 'b' in this equation, first, multiply both sides by 7 to isolate '18b': 18b = 536 * 7 18b = 3752 Now, divide by 18 to find the value of 'b': b = 3752 / 18 b = 208

5. c = 9 This equation is already solved, and 'c' is equal to 9.

So, the solutions are as follows:

• x = 34
• x = 31/27 (or approximately 1.148)
• y = 2/103
• b = 208
• c = 9
