This storyboard does not have a description.
I going to fail this test omg I do NOOOT understand this
Nonono you're just eliminating a number it's very simple, it just looks dificult
But how would that look?
the main idea is that we can eliminate a variable using addition or subtraction
6x +3y =11 x +3y =1 __________________
you would set every equation like this, than add or subtract the numbers that are the same to cancle out the number. Whatever you used to cancel out that pare that are the same, you would use to find the next set of number.
but what if the ewuations have totally diffrent numbers?
Than all you'd have to do is divide the two numbers that are left, and take the variable that you got from that problem and plug it into the one of the other equations.
If that's the case than all you'd have to do is multiply all of the numbers in one equation buy any number that would get either X or Y to be the same.
I get it now!!! THANK YOU
Let's go ace that test!
