How to solve Solving Systems of Equations by Elimination

Storyboard Text

  • Today kids, we are going to be talking about Solving Systems of Equations by Elimination.
  • How do we solve that kind of problem Mr.Tveter?
  • Example Use Elimination to Solve the System 2x+y=12 -3x+y=2
  • Use the Opposite of the bottom line to solve. Example- 2x+y=12 3x-y=-2
  • Now add/subrtract the lines Example- Do 2x+2x, y -y, and 12-2. That now equals 5x=10. X would then equal 2.
  • Now plug the x=2 into either the top of the bottom problem. Y=8. Ex-  2(2)+y=12  OR -3(2)+y=2 Then Put the 2 numbers you get into coordinates. Example- (2,8)
