In the equation \( 18x - 12 = 4 \), the step that is NOT involved in solving for \( x \) is "canceling the 18s".
The correct steps typically are:
1. Add 12 to both sides: \( 18x - 12 + 12 = 4 + 12 \) → \( 18x = 16 \)
2. Then, divide both sides by 18: \( x = \frac{16}{18} \) → \( x = \frac{8}{9} \)
So, the response "canceling the 18s" does not apply in this context, as it is not a legitimate step in solving the equation.
