I  used  this  foldable  to  introduce  equa+ons  

with  infinitely  many  

solu+ons  and  no  solu+on.

Solve  each  equa+on.    Show  all  work  clearly  and  circle  your  final  answer.    Equa+ons  may  have  one  solu+on,  no  solu+on,  or  be  an  iden+ty  with  infinite  solu+ons.  

Objec+ve:  Students  will  solve  mul+-­‐step  equa+ons  having  one  solu+on,  no  solu+on,  or  infinite  solu+ons.
