Simple equation solving in C

I found that the void main isn't correct but even when I change it to int or erase it,

I'm not getting what I'm supposed to which is the value for X given the values for A and B for the equation ax+b=0 and all I get are zeroes.

How can i fix this ?

void main()
{
    float a,b,x=0;
    printf("\n Write the values for A and B");
    scanf("&%F&%F",&a,&b);
    if(a==0)printf("\n Not a valid operation");
    else{x=-b/a;
        printf("\n Answer is x=%f",x);
    }
}

Try 

scanf("%f%f",&a,&b);

instead of

  scanf("&%F&%F",&a,&b);

Your use of the format specifiers to read a and b seem strange. Not sure whether you meant to have those & in there. Checkout the details of the valid format specifiers at http://en.cppreference.com/w/cpp/io/c/fscanf.

Try:

scanf("%f%f",&a,&b);

& is not a format specifier. When you use

scanf("&%F&%F",&a,&b);

scanf expects the characters & in the input stream.
