Hi students! Today we are learning about systems of equations.
Does anyone know how to solve systems of equations by elimination?
Noo! Nooo! Noo!
Brooke and Britney arrive at school they are excited because they are going to learn about systems of equations in math today
4x+2y= 10 - x +2y=1 2y-2y=o 3x=9 X=3
Mr. Tveter asks the student if anyone knows how to do the equations but none of the students know how.
3 + 2y =1 -3 -3 2y=-2 Y=-1
This makes Mr. Tveter sad. Then his fellow teachers Ms. Sites and Ms. Terrill tell him he can teach them how. But Mr. Smith doesn't like math until Mr. Tveter teaches the history of math then everyone is happy. Now he can teach his class systems of equations.
Mr. Tveter tells his class to use adding or subtration to eliminate the varible the find X
Then he says to find y by plugging x into the equation. So the answer is (3,-1)
Brooke and Britney now know how to solve equations by elimination.
