Solving One-­‐Step Equations in One Variable Directions: For each equation below, solve for the variable. Remember to use your questions. 1) What is my goal? To get the variable alone 2) What number(s) are keeping the variable from being alone? 3) How are those numbers attached to the variable? (which operations: + , -­‐ ,* or ÷) 4) How do I undo those operations? Use the inverse operation 5) Which operation should I undo first? (listen to SADM…this is not necessary for a one-­‐step equation) SHOW ALL WORK!!! 1) 4x = 24 2) 3x = 7 3) -­‐2x = 6 4) x + 7 = 12 5) -­‐ 4 + x = -­‐ 10 6) x – 10 = 1 !
