Step 1: Draw a Line down the equal sign 

Step 2: Circle your variable 

Step 3: Look at the number next to your variable separated by a PLUS OR MINUS ONLY. 

Step 4: Do the opposite sign to both sides. (ONLY PLUS OR MINUS) 

Step 5: Circle your variable ONLY 

Step 6: Do the opposite sign to both sides (ONLY MULTIPLICATION OR DIVISION)
