Storyboard Text

• Heres the receipt. What does ﻿2x + y= 1 and 4x + 2y=2
• Well the best way to solve that problem would be to use something called the elemation method﻿
• ﻿Then both of the problems are the same and all you have to do is subtract 4x+2y=4 - 4x + 2y=2 So you get 0=2 Which is a No Solution Incosistent
•  I know how to do that first you have to multiply 2x +y=1 so that the problem is the same as 4x+2y=4 ﻿
• That receipt makes no sense there's another problem on it maybe this one will work 2j+K=3 K=j-9
• So first you plug in j-9 for k using the substitution method and get 2j+j-9+9 then add like terms 3j-9=3 then add 3 and get 12 then divide 3j=12 so J=4﻿
• Thats great but you still need to find K so to make it easier im using the second problem K=j-9 Plug in 4 for J K=4-9 so K= -5﻿
• Ok sure!﻿
• ﻿Great! Since your so good at math do you want to help me with some graph homework
• Thats an Infinte Solution they have the same slop and same y-int﻿
• Thanks!﻿
• Thats No Solution! Ready to get going﻿
• Yep thanks!﻿
