  • Introduction
  • Wait, how do you solve the system of equations elimination method?
  • Good question, let me show you
  • Step 1
  • The first thing you should do is find a number that you can mutilpy by the first equation that is going to help you with the second one
  • Step 1 example
  • Example: ( 4x-4y=8 ) *3 ( 10x+3y=-19 ) *4
  • Step 2
  • The next thing you do is add up the two equations to get X
  • Step 2 example
  • Example: 12x-12y=24 40x+12y=-76 52x=52 x=-1
  • Step 3
  • The last step is to find y. You plug x into one of the equations to get y. So the solution is   (-1, -3 )
  • Thank you, that was so easy!!!!
