Answer 1

54 + 63 - 30 =87
подтверждение: 87 - 63 + 30 = 54

Answer 2

Problem Analysis

To solve this problem, we need to find the original number that was increased by 30 and then decreased by 63 to result in 54. Let's break down the problem step by step.

Solution

Let's assume the original number is x.

1. The number was increased by 30, so we have x + 30. 2. The result was then decreased by 63, so we have (x + 30) - 63. 3. The final result is 54, so we can set up the equation: (x + 30) - 63 = 54.

Now, let's solve this equation to find the value of x.

(x + 30) - 63 = 54

Simplifying the equation:

x + 30 - 63 = 54

x - 33 = 54

Adding 33 to both sides:

x = 54 + 33

x = 87

Therefore, the original number that was initially increased by 30 and then decreased by 63 to result in 54 is 87.

Conclusion

The original number that was initially increased by 30 and then decreased by 63 to result in 54 is 87.
