• 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!!!!﻿
