Ms. Wilson should subtract 12x from both sides of the equation.
To correctly solve the equation 7x - 4 = 12x + 40, Ms. Wilson should subtract 12x from both sides of the equation. This is because the goal is to isolate the variable, 'x', on one side of the equation. By subtracting 12x from both sides, the x terms will be eliminated from the right side of the equation.
So, the correct answer is:
Subtract 12x from both sides of the equation.
