#include <iostream>
using namespace std;

int main()
{
	float x;		  //price of item
	double y = 0.06;   //sales tax
	float slstax;
	float total;

	cout<<"input your item's price";
	cin>>x;

	x * y = slstax;
	x + slstax = total;

	cout<<"this is your final price, in pennsylvania"<<total<<endl;
	return 0;
}

i am believing that something HAS to go infront of the x in both of these statements but...idk... help would be great! :D ty in advance!

Change it to:

slstax = x * y;
total = x + slstax;
