  • AOpen the brackets using the distributive property
  • BDivide both sides by
  • CAdd 4 to the left side only
  • DSquare both sides

Step-by-Step Solution

When an equation contains brackets, the recipe says to open them first: .
Answer: A) Open the brackets using the distributive property

Key idea: The five-step recipe

For any linear equation in one variable, follow this order:

1. **Open brackets** if any (use distributive property).
2. **Clear fractions** by multiplying both sides by the LCM of all denominators.
3. **Move all variable terms to one side**, all constants to the other (transposition — flip signs).
4. **Combine like terms** on each side.
5. **Divide** both sides by the coefficient of the variable.

Then **verify** by substituting back into the original equation. Always.
