Fill in the blanks with the correct numbers to complete the equations: 17 - 9 = ... = 16 - ... = ... - 4 6 + 7 = ... = 8 + ... = ... + 4 8 + 6 = ... = 7 + ... = ... + 9 13 - 5 = ... = 14 - ... = ... - 3

Let's solve each equation step by step.

1. 17 - 9 = ... = 16 - ... = ... - 4

   First, calculate 17 - 9: $$17 - 9 = 8$$

   Now we know that the first blank should be filled with 8. The equation now looks like this: $$8 = 16 - ...$$

   To find the missing number, we calculate 16 - 8: $$16 - 8 = 8$$

   So, the second blank should be filled with 8. The equation now looks like this: $$8 = 8 = ... - 4$$

   To find the missing number, we calculate 8 + 4: $$8 + 4 = 12$$

   So the final equation is: 17 - 9 = 8 = 16 - 8 = 12 - 4

2. 6 + 7 = ... = 8 + ... = ... + 4

   First, calculate 6 + 7: $$6 + 7 = 13$$

   Now we know that the first blank should be filled with 13. The equation now looks like this: $$13 = 8 + ...$$

   To find the missing number, we calculate 13 - 8: $$13 - 8 = 5$$

   So, the second blank should be filled with 5. The equation now looks like this: $$13 = 8 + 5 = ... + 4$$

   To find the missing number, we calculate 13 - 4: $$13 - 4 = 9$$

   So the final equation is: 6 + 7 = 13 = 8 + 5 = 9 + 4

3. 8 + 6 = ... = 7 + ... = ... + 9

   First, calculate 8 + 6: $$8 + 6 = 14$$

   Now we know that the first blank should be filled with 14. The equation now looks like this: $$14 = 7 + ...$$

   To find the missing number, we calculate 14 - 7: $$14 - 7 = 7$$

   So, the second blank should be filled with 7. The equation now looks like this: $$14 = 7 + 7 = ... + 9$$

   To find the missing number, we calculate 14 - 9: $$14 - 9 = 5$$

   So the final equation is: 8 + 6 = 14 = 7 + 7 = 5 + 9

4. 13 - 5 = ... = 14 - ... = ... - 3

   First, calculate 13 - 5: $$13 - 5 = 8$$

   Now we know that the first blank should be filled with 8. The equation now looks like this: $$8 = 14 - ...$$

   To find the missing number, we calculate 14 - 8: $$14 - 8 = 6$$

   So, the second blank should be filled with 6. The equation now looks like this: $$8 = 14 - 6 = ... - 3$$

   To find the missing number, we calculate 8 + 3: $$8 + 3 = 11$$

   So the final equation is: 13 - 5 = 8 = 14 - 6 = 11 - 3

Therefore, the completed equations are:

1. 17 - 9 = 8 = 16 - 8 = 12 - 4
2. 6 + 7 = 13 = 8 + 5 = 9 + 4
3. 8 + 6 = 14 = 7 + 7 = 5 + 9
4. 13 - 5 = 8 = 14 - 6 = 11 - 3

Answer:

1. 17 - 9 = 8 = 16 - 8 = 12 - 4
2. 6 + 7 = 13 = 8 + 5 = 9 + 4
3. 8 + 6 = 14 = 7 + 7 = 5 + 9
4. 13 - 5 = 8 = 14 - 6 = 11 - 3
