Solving Equations by Elimination
This storyboard does not have a description.
I would like to discuss solving equations by elimination.
Ok what would you like to discuss
how would you solve the equation 5x+5y=19 5x+y=7
I would Subtract the five X from the other five X and then do the same to the 5Y and Y then subtract 7 from 19
Then what would you do after you get that equation?
then I would end up with 4y=12
What would you do after that?
I would then divide the 4 by itself and also divide the twelve by the four.
what would your answer then be?
My answer would then be y=3
That is how you solve a systems equation by elimination.
