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
