First, let's simplify the equation you provided:
Starting with the equation: \[ 3 - 15x + 24 + 16x = 4x - 24 - 4x \]
Combine like terms on the left side: \[ (3 + 24) + (-15x + 16x) = 4x - 4x - 24 \] \[ 27 + x = -24 \]
Now we have: \[ 27 + x = -24 \]
To isolate \( x \), the next best step would be to subtract 27 from both sides:
So, the correct response is: Subtract 27 from both sides of the equation.
