the first step to solving this is to move the variable to the left side of the equation and change its sign -4x - 18 = 2 now youll need to move the constant to the right side of the equation and change its sign -4x = 2 + 18 next,, add the numbers -4x = 20 and then divide both sides of the equation by -4 x = -5 the correct answer to your question is x = -5 let me know if you have any further questions :)
