Answer 1

#include <iostream>

using namespace std;

int main(){

double x=0,a,b;

cout<<"Dati coef. a:";

cin>>a;

cout<<"Dati coef. b:";

cin>>b;

cout<<"Ecuatia obtinuta: "<<a<<"X";

if(b<0){

   cout<<b<<"=0"<<endl;

} else if(b>0){

   cout<<"+"<<b<<"=0"<<endl;;

}

if((b>0 && a>0)||(b<0 && a<0)|| (b<0 && a>0)){

   x=(-b/a);

}

if((b>0 && a<0)){

   x=b/a;

}

if(b>0 && a<0){

   x=b/-a;

}

if(b==0 || a==0){

   x=0;

}

cout<<"X="<<x;

return 0;
