Answer 3

1) 3452 - x = 768 + 987

To solve for x, we can start by simplifying the right-hand side of the equation.

Step 1: Combine 768 and 987: 768 + 987 = 1755

Step 2: Substitute 1755 into the equation: 3452 - x = 1755

Step 3: To solve for x, we can isolate x by subtracting 3452 from both sides of the equation: 3452 - 3452 - x = 1755 - 3452 -x = -1697

Step 4: Multiply both sides by -1 to solve for x: x = 1697

So, the solution for the first equation is x = 1697.

2) У + 30 = 4085 + 2365

Following a similar process, we can solve for У.

Step 1: Combine 4085 and 2365: 4085 + 2365 = 6450

Step 2: Substitute 6450 into the equation: У + 30 = 6450

Step 3: To solve for У, we can isolate У by subtracting 30 from both sides of the equation: У + 30 - 30 = 6450 - 30 У = 6420

So, the solution for the second equation is У = 6420.

3) (9805:5 - 193 + 267 × 342):3

To solve this expression, we can follow the order of operations (parentheses, multiplication and division from left to right, addition and subtraction from left to right).

Step 1: Perform the operations inside the parentheses: 9805 ÷ 5 - 193 + 267 × 342 = 1961 - 193 + 91414

Step 2: Combine the values: 1961 - 193 + 91414 = 1778 + 91414

Step 3: Perform the addition: 1778 + 91414 = 93192

Step 4: Perform the final division operation: 93192 ÷ 3 = 31064

So, the result of the expression (9805 ÷ 5 - 193 + 267 × 342) ÷ 3 is 31064.

4) 288648 ÷ 72

Simply performing the division operation: 288648 ÷ 72 = 4013

So, the result of the division 288648 ÷ 72 is 4013.

5) 61983 ÷ 97

Simply performing the division operation: 61983 ÷ 97 ≈ 639.2474

So, the result of the division 61983 ÷ 97 is approximately 639.2474.
