First subtract x from both sides to move x on the left to the right. Next you have to add the negitive x to neitive 7 to get negitive 8. After you move everything down you divide negitive 8 feom both sides of the equation to get x alone. Finailly you get -3.375=x as your final answer. If you need to round then the answer is -3.38=x. Hopefully this is right and helps
