Inverse Operations and the Properties of Equality Worksheet with Answer Key

What's on the worksheet

1. Fill in each blank with the operation and number that undoes the first step.
2. Do each move to both sides of 18 + 6 = 24 and say if the new sentence is true.
3. Say what to do to both sides of each equation and name the property.
   p + 2.4 = 9\dfrac{h}{7} = 3.55g = 3225 = d - 13\dfrac{3}{4} + k = 2
4. Work backward to the equation Ava started with from one move.
   Subtracted 14 from both sides, got x = 9Divided both sides by 6, got y = 4.5Multiplied both sides by 3, got z = 12Added 2.5 to both sides, got w = 10
5. Word problem: write an equation for washers balancing masses on a balance.
6. Pick which equations are equivalent to x + 9 = 21 and name the move.
7. Check each student's wrong answer and name the move that should have been made.
