Hope this helped.

Answer 2

To find the answer the question first write it out. 3*x-5=40. move the five over next to the 40 and cancel out -5. so the new equation looks like this. Then add 40+5 which is 45.Lastly you have the number 3 and the variable x. now you have to divide 3 by 45 to get your final answer 15. so x=15.

                                                                            3*x=40+5

                                                                            3*x=45

Hope this helps!!
