Solving  One-­‐Step  Equations    

Name:  ____________________________________       Date:  ______________________________      Which  property  of  equality  would  you  use  to  solve  each  equation?  Why?    1)  3+ 𝑥 =  −34  _______________________________   2)  2𝑥 = 5    _______________________________      3)  𝑥 − 4 = 9    _______________________________     4)  !

!= 9          _______________________________  

   Solve  the  equation  and  check  your  solution.    5)  6 = 𝑥 − 2     6)  27+ 𝑛 = 46                      7)  23 = 𝑣 − 5     8)          4 = 𝑞 + 13                          9)    −17 = 3+ 𝐾   10)    𝐶 + 4 =  −9                    11)  −67 = 𝑤 − 65   12)      𝑗 − 3 =  −7

Solving  One-­‐Step  Equations    

Define  a  variable  and  write  an  equation  for  each  situation.  Then  solve.    21)  You  have  a  rack  that  can  hold  30  CD’s.  You  can  fit  7  more  CD’s  on  the  rack  before  the  rack  is  full.  How  many  CD’s  are  in  the  rack?                22)  An  online  DVD  rental  company  offers  gift  certificates  that  you  can  use  to  purchase  rental  plans.  You  have  a  gift  certificate  for  $30.  The  plan  you  select  costs  $5  per  month.  How  many  months  can  you  purchase  with  the  gift  certificate?                23)  At  a  party  of  102  people,  72  lb  of  potato  salad  is  served.  Write  and  solve  an  equation  to  find  how  many  people  each  pound  of  potato  salad  serves.
