crammer code

Code:

---

int number
int a;
int b;
int c;
int d;
int e;
int f;//values of intergers
double x1 ;//value of x
double z ;// value of x1/x2
double y1 ;//value of y

cout << "Please enter integers values for a " << endl;

cin >> number;
cout << "Please enter integers values for b " << endl;
cin >> number;
cout << "Please enter integers values for c " << endl;
cin >> number;
cout << "Please enter integers values for d " << endl;
cin >> number;
cout << "Please enter integers values for e " << endl;
cin >> number;
cout << "Please enter integers values for f " << endl;
cin >> number;
x1 =e*c-f*b ;
z=a*e-b*d ;
y1=a*f-d*c;


cout << "x = " << z/x1 << endl;
cout << "y = " << z/ y1 << endl;

im trying to put this equations
x = (c e - f b) / D and y = (a f - d c) / D
and x = a e - b d.
its the crammer rule but i cannot figure out how to put it on a c++ program any help is not coming up right this is what i got

Code:

---

//i assume d is D and two letters together means to multiply them
x = ((c * e) - (f *b) / d
y = ((a * f) - (d * c)) / d
x = (a *e) - (b * d)

Reading multiple values to number (cin >> number) does not insert values into variables a,b,c,d,e, or f.
