Let's solve the equation step by step and fill in the missing terms and descriptions.
-
Start with the original equation:
-
Apply the distributive property:
(because ) -
Now we have:
-
Next, we subtract 7 from both sides:
-
Combine like terms:
So the completed steps with filled-in missing terms and descriptions are as follows:
- Equation:
- Apply the distributive property:
- Subtract 7 from both sides:
- Combine like terms:
Missing Descriptions:
- Multiply both sides by 3 (not used, as we divided both sides by 3 instead)
- Add 3 to both sides (not used, as we didn't need to add 3)
- Subtract 3 from both sides (not used)
- Divide both sides by 3 (used)
- Subtract 7 from both sides (used)
