Storyboard Text

  • Emm... Son, do you need help?
  • I don't think you know equation systems 
  • You bet I can do it. Bring it 
  • Well, can you help me with equation systems?  
  • Let me think how I can explain you
  • Okay, it says that: x+2y= 40 and 2x+y=50
  • I know! Imagine that one chocolate and two ice creams costs 40 and two chocolates and one ice cream 50
  • 2(x+2y=40) -1(2x+y=50) 4y=80 -y=-50 3y=30 y=10
  • -1(x+2y=40) 2(2x+y=50) -x=-40 4x=100 x=25
  • Well, the chocolate cost $25 and the ice cream $10?
  • I think that now you understand 
  • OMG, so easy an I couldn't understand until now 
  • Let's go have dinner!
  • Yup, i'm hungry
