Answer 1

32+5х3=15+32
81-7х4 =9х9 -28
54:(10-4)=72:8
42:7-6=3-3
54:9+72=6+9х8
8х7+28=28+56

Answer 2

32 + 5 * 3 = 47 32 + 81 - 7 * 4 = 81 9 * 9 - ? = 81 ? : (10 - 4) = 72 : 8 + 42 : 7 - ? = 3 -3 + 54 : 9 + ? = 6 + 9 * 8 + 8 * 7 + 28 = 28 + ? + 8

Let's solve each equation step by step:

Equation 1: 32 + 5 * 3 = 47

To solve this equation, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). In this case, we start with the multiplication: 5 * 3 = 15. Then, we add 32 to 15, resulting in 47.

Equation 2: 32 + 81 - 7 * 4 = 81

Again, we follow the order of operations. First, we perform the multiplication: 7 * 4 = 28. Then, we add 32 and 81, resulting in 113. Finally, we subtract 28 from 113, giving us 85.

Equation 3: 9 * 9 - ? = 81

To find the missing value, we need to solve for "?". We know that 9 * 9 equals 81, so the missing value is 0.

Equation 4: ? : (10 - 4) = 72 : 8 + 42 : 7 - ? = 3

This equation has two parts separated by the "=" sign. Let's solve each part separately.

Part 1: ? : (10 - 4) Inside the parentheses, we have 10 - 4 = 6. So, the equation becomes ? : 6. We don't have enough information to solve for "?", as we don't know the value of "?". Therefore, we cannot determine the result of this equation.

Part 2: 72 : 8 + 42 : 7 - ? First, we perform the divisions: 72 : 8 = 9 and 42 : 7 = 6. Then, we add 9 and 6, resulting in 15. Finally, we subtract "?", which we don't know, from 15. Therefore, we cannot determine the result of this equation.

Equation 5: -3 + 54 : 9 + ? = 6 + 9 * 8 + 8 * 7 + 28 = 28 + ? + 8

This equation also has two parts separated by the "=" sign. Let's solve each part separately.

Part 1: -3 + 54 : 9 + ? First, we perform the division: 54 : 9 = 6. Then, we add -3 and 6, resulting in 3. Finally, we add "?" to 3. We don't have enough information to determine the value of "?".

Part 2: 6 + 9 * 8 + 8 * 7 + 28 We follow the order of operations. First, we perform the multiplications: 9 * 8 = 72 and 8 * 7 = 56. Then, we add 6, 72, 56, and 28, resulting in 162.

Therefore, the equation becomes 28 + ? + 8 = 162. To solve for "?", we subtract 28 and 8 from 162, resulting in ? = 126.

Summary:

- Equation 1: 32 + 5 * 3 = 47 - Equation 2: 32 + 81 - 7 * 4 = 85 - Equation 3: 9 * 9 - ? = 81 (missing value: ? = 0) - Equation 4: ? : (10 - 4) = 72 : 8 + 42 : 7 - ? = 3 (cannot be determined) - Equation 5: -3 + 54 : 9 + ? = 6 + 9 * 8 + 8 * 7 + 28 = 28 + ? + 8 = 162 (missing value: ? = 126)

I hope this helps! Let me know if you have any further questions.
