#### Storyboard Text

• My name is Junjie
• ﻿so... Ms.Chen? why are we facing a paint board?﻿
• As a "MATH" teacher my job is to teach student how to do math!
• Hi,my name is Ms.chen﻿
• What exactly is multi-step equation?﻿
•  Multi-step equation is the use properties of equality together to isolate variables and solve algebraic equations.
• W﻿e are facing the paint board because we are going to learn multi-step equation!
• So,how do you do this type of equation??
• I see in this equation there is variables in both side of the equation...
• Let's solve the equation 2(4X+5)=2(2X+4)+4X+2
• There are many steps and different ways to solve a multi-step equation﻿
• ﻿I know that we can't combine like terms beacuse the number 10 don't have a X
•  I know that we still need to combine like terms  4X+4X will get 8X,and 2+8=10.The answer will be 8X+10﻿
• Next,we will need to do the same thing on the right side of the equation,so we do distributive property 2 times 2X will get 4X,and 2 times 4 will get 8.
• First,we will need to distributive property on the left side.2 times 4x will equal to 8X,and 2 times 5 is 10.The answer will be 8x+10﻿
• ﻿I could like to get the variable by itself on the left side.We do the inverse operation of 8X which is division so 8X dived by 8X will elimates.
• We see that both side equals to 8X+10,we continue to solve it by doing inverse operation to get the variables on one side of the equation
• Now,there is only 10 in the left and 10 in the right in the equation.﻿We do inverse operation of 10 which is subtract 10 each side will equal to 0.
• Thank you Ms.Chen for teaching me how to do multi-step equation,I promise next time I will teach someone that needs help with this.﻿
• Oh,solving a multi-step equation could take many different step to get the final answer﻿
• ﻿The answer to this multi-step equation is infinite solution.A infinite solution could mean that any number can be X and both side will equal to each other.
• Junjie I hope that you will know how to do this type of equation  next time when he see this type of equation. ﻿
