Question

Испытание на 100 баллов (вам везёт):1+(-4)-(-3)=(-3+(-7))+(7-12)=Разгадайте ребус:А+5+А+12=37Кто будет писать какую-то ерунду в ответе, тому нарушение будет (хуже будет).Не пропустите!

Answer 1

1+(-4)-(-3)=1-4+3=0

(-3+(-7))+(7-12)=(-3-7)+(7-12)=-10-5= -15

А+5+А+12=37
2А=20
А=10

Answer 2

It looks like you've presented a series of mathematical equations and a riddle. Let's break it down step by step.

Mathematical Equations:

1. Solve the equation -4 - (-3): - The solution to -4 - (-3) is -1. [[1]]

2. Solve the equation -3 + (-7) + 7 - 12: - The solution to -3 + (-7) + 7 - 12 is -15. [[2]]

Riddle:

The riddle presented is "A + 5 + A + 12 = 37." To solve this, we can combine like terms: - A + A + 5 + 12 = 37 - 2A + 17 = 37 - 2A = 37 - 17 - 2A = 20 - A = 20 / 2 - A = 10

So, the value of A in the riddle is 10.

I hope that helps! If you have any more questions or need further assistance, feel free to ask.
