  • Hello what can I help you with?
  • I Was looking for the cash register. Can you help me find it?
  • Um, sure no problem!
  • Thank you !
  • Unfortunately theirs only one problem. Our registers can only open if you solve a multi step equation which is -8(n-9)+(4n+5)=8-1n
  • Ow snap! can you help me with the problem?
  • Yeah sure! So the first step to solve the equation is to distribute and do -8n x n and -8 x 9. After that you cant distribute anymore so you add -8n + 4n and 72 + 5. As a result, you get the equation -4n + 77=8-1n where you would do-4n + 1 and get -3.
  • That's Cool!
  • Once your done with that you bring down all the remaining numbers and have the equation-3n + 77=8 . After that you do the inverse operation once again and do 77 - 8 and get -69 and then finally divided by -3 and get 23, your final answer.
  • Thank You! your a life saver!!
  • Is their anything else I could help you with?
  • No, but thanks for the money and good luck lookin g for a new job once your fired from  this one!!
