How to solve Solving Systems of Equations by Elimination
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)
