Let's first simplify the equation by combining like terms:
Starting with the equation: \[ 3 - 15x + 24 + 16x = 4x - 24 - 4x \]
Combine terms on both sides:
-
On the left side: \[ 3 + 24 = 27 \] \[ -15x + 16x = 1x \] So, the left side simplifies to: \[ 27 + 1x = x + 27 \]
-
On the right side: \[ 4x - 4x = 0 \] Therefore, the right side simplifies to: \[ -24 \]
Now, the equation is: \[ x + 27 = -24 \]
The next best step to finish solving the equation is to isolate \( x \). In this case, to do that, we can subtract 27 from both sides of the equation.
Hence, the correct response is: Subtract 27 from both sides of the equation.
