Solving the Equations

To solve the equations and fill in the missing arithmetic signs, let's examine the given equations and their solutions:

1) 7 _ 4 _ 8 _ 2 = 32 2) 7 + 4 _ 8 _ 2 = 37 3) (7 _ 4) _ 8 _ 2 = 22

Let's solve each equation step by step:

1) 7 _ 4 _ 8 _ 2 = 32 To find the missing arithmetic signs, we can start by evaluating the expression inside the parentheses: 7 _ 4. Since the result is not given, we can assume it to be a multiplication operation. Therefore, the equation becomes: 7 * 4 _ 8 _ 2 = 32. Now, we can evaluate the remaining operations: 7 * 4 = 28, so the equation becomes: 28 _ 8 _ 2 = 32. To find the missing sign between 28 and 8, we can subtract 8 from 28: 28 - 8 = 20. Therefore, the equation becomes: 20 _ 2 = 32. To find the missing sign between 20 and 2, we can subtract 2 from 20: 20 - 2 = 18. Therefore, the final equation is: 18 = 32.

2) 7 + 4 _ 8 _ 2 = 37 To find the missing arithmetic signs, we can start by evaluating the addition operation: 7 + 4 = 11. Therefore, the equation becomes: 11 _ 8 _ 2 = 37. To find the missing sign between 11 and 8, we can subtract 8 from 11: 11 - 8 = 3. Therefore, the equation becomes: 3 _ 2 = 37. To find the missing sign between 3 and 2, we can subtract 2 from 3: 3 - 2 = 1. Therefore, the final equation is: 1 = 37.

3) (7 _ 4) _ 8 _ 2 = 22 To find the missing arithmetic signs, we can start by evaluating the expression inside the parentheses: 7 _ 4. Since the result is not given, we can assume it to be a subtraction operation. Therefore, the equation becomes: (7 - 4) _ 8 _ 2 = 22. Now, we can evaluate the remaining operations: 7 - 4 = 3, so the equation becomes: 3 _ 8 _ 2 = 22. To find the missing sign between 3 and 8, we can subtract 8 from 3: 3 - 8 = -5. Therefore, the equation becomes: -5 _ 2 = 22. To find the missing sign between -5 and 2, we can subtract 2 from -5: -5 - 2 = -7. Therefore, the final equation is: -7 = 22.

Summary

After solving the equations and filling in the missing arithmetic signs, we found that the equations do not have valid solutions. The equations do not hold true, and the given values do not satisfy the equations.
