Storyboard Text

  • Hi class of 2017 today we will be learning about combining like terms.
  • OK I think this is going to be hard
  • Hi ok
  • Hi ok
  • Ok
  • Solve this please  7 ( m - 2 ) + 21 = 2m +3
  • Now you subtract -7 and -7 on positive 3.
  • I fell like I an getting it.
  • Finally you should get 5m = 7. Than you should divide by 5 on both sides and the final answer you should get it is m = -4/5
  • First you use distributive property 7 ( m + 2 ) next you combine like terms.
  • You should be able to get 7m + 7 = 2m + 3. Now you do -2m on -2m and do it on 7m. Then you should be able get 5m + 7 = 3. 
  • Wait shouldn't you leave it like that or you have to do somthing else.
  • No you have to divide because it says simplify as much as you can
