  • okay miss mia
  • Hello class. My name is Mia, but call Miss Mia.Today we learn how to solve multi-step equations.
  • I think we first do distributive property because we multiply number outside of the parentheses. 
  • Let try  4(2a+3)=-3(a-1)+3. What do we do first?
  • Yes Max, so that mean it going to be 8a+12=-3a+3+31. Then what do we now?
  • We need to combine like terms, like 3+31 are the same number so you could add them. another thing is that they are on the same side.
  • So it going to be 8a+12=-3a+34.  Then we move the variables on one side so we will add 3a because the other 3a is a negative and we want to get rid of the variable to have one variable and not two.It going to be 11a+12=34
  • Then we move the constant, the number next to the variable but not attached
  • Yes that mean we subtract 12 because it next the variable but not attached. it will be 11a=22. then what do we now?
  • Last we move the coefficient, the number attached to the variable
  • Yes that mean we divide 22 by 11 and the answer is a+2. 
  • We could check our work to .
  • YES
  • Yes but let do that another time. Did you learn something
