The left-hand side of an assignment must be a variable, a property or an indexer

I looked at other threads, but could not find an answer.

The error is on line 6, 7 and 8.
Could someone help me out?

using UnityEngine;
using System.Collections;

public class SaveLoad2 : MonoBehaviour {

	public void SaveLocation (Vector3 pos){ //Where pos is the position of the player
		PlayerPrefs.SetFloat("playerX") = pos.x;
		PlayerPrefs.SetFloat("playerY") = pos.y;
		PlayerPrefs.SetFloat("playerZ") = pos.z;
	}
	
	
	//Handles Load - Returns Vector3
public	Vector3 GetLocation(){
		return new Vector3(PlayerPrefs.GetFloat("playerX"), PlayerPrefs.GetFloat("playerY"),PlayerPrefs.GetFloat("playerZ"));
	}

}

your syntax is wrong - check the docs.

PlayerPrefs.SetFloat("name", value);
