So first step: simplify like terms. Since you have two like terms on the same side then you just add them together. Your equation now looks like this: -9=11x+24. Then you subtract 24 from both sides to get -33=11x. Divide both sides by 11(the coefficient of x), and you get -3=x. I hope my steps are clear enough and this is helping you. If you really don’t get it you should ask your teacher. It would really help you.
