Объяснение:

1+2÷(1+32÷(1+1024÷(1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x)))))))=1987

2÷(1+32÷(1+1024÷(1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x)))))))=1987-1

1+32÷(1+1024÷(1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x))))))=2/1986

32÷(1+1024÷(1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x))))))=1/993 -993/993

1+1024÷(1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x)))))=32·(-993/992)

1024÷(1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x)))))=-993/31 -31/31

1+32÷(1+2÷(1+2÷(1+2÷(1+2÷x))))=1024·(-31/1024)

32÷(1+2÷(1+2÷(1+2÷(1+2÷x))))=-31-1

1+2÷(1+2÷(1+2÷(1+2÷x)))=32/(-32)

2÷(1+2÷(1+2÷(1+2÷x)))=-1-1

1+2÷(1+2÷(1+2÷x))=2/(-2)

2÷(1+2÷(1+2÷x))=-1-1

1+2÷(1+2÷x)=2/(-2)

2÷(1+2÷x)=-1-1

1+2÷x=2/(-2)

2/x=-1-1

x=2/(-2)

x=-1
