- I like to play hockey. Food that is not good for me I still eat all the time, doritos and goldfish. I think it is cool when you watch Monday Night Football and the players give respect to their high school instead of college. WOW, that is the type of high school Norton should be, so amazing you want to mention how great it is whenever you can.

Hey Mr. Grasso i just wanted to say that i am stll having trouble wth the homework. I am having lots of trouble understanding. If you or someone else could help me that would be great! Thanks!
alright if your having trouble with elimination, i'll do an example from the homework tonight.
#14
3m-2n=13
m+2n=7
alright the first step to do is to eliminate the easiest.
its basically set up like an addition problem
3m-2n=13
m+2n=7
_______
you want to find the opposites which are -2n and 2n so they cancel out. so now you have an equation. then add them up
3m=13
m=7
_______
4m=20
then divide 4 from both sides
m=5
so then you want to substitute m=5 to either equation.we are going to find n now.
m+2n=7 so substitute m=5 in
5+2n=7 then solve
-5 -5
2/2n=2/2
n=1
so your solution is (5,1)
i hoped this helped
Joe excellent explanation. I think this your picture is great... Is that you? Anyway that was a great job... Cassie did this help?
I liked how you decided to "substitute back into the equation and not eliminate all ovre again. Great use of your time. See you in class tomorrow.
