Let's solve each equation step by step to identify the correct responses:
Question 1: Solve the equation \( x + 12 = 42 \)
To isolate \( x \), we need to subtract 12 from both sides:
\[ x + 12 - 12 = 42 - 12 \] \[ x = 30 \]
The true statement is: Subtract 12 from both sides of the equal sign. x = 30.
Question 2: Solve the equation \( x - 6 = 18 \)
To isolate \( x \), we need to add 6 to both sides:
\[ x - 6 + 6 = 18 + 6 \] \[ x = 24 \]
The true statement is: Add 6 to both sides of the equal sign. x = 24.
Summary of True Statements:
- For Question 1: Subtract 12 from both sides of the equal sign. x = 30.
- For Question 2: Add 6 to both sides of the equal sign. x = 24.
