it's annoying... why learn all of that crap when the only reason in our entire lives we need to know it is to solve the stupid ******** problems they assign us in the first place
USELESS ... and easily voided from the mind once no longer necessary

I couldn't agree more xp
But of course teachers enjoy tormenting us. And they have the strange gene that gives them the idea that we "need" to learn these things... confused I disagree with this. xd

I tried studying it myself, but the textbooks examples and explanations are of little to no use.

oh well i can tell who how your supposed to do it but i never end up with the right awnser sweatdrop
first you pick either one or the other of the two equations and solve for either x or y
so like for 3x+2y= 25 you could subtract 2y from both sides and get
3x=-2y+25 hen divide by 3
y=-2/3x+25/3
(hates fractions)
then since you have an y value you can go and plug it back into the other problem
like 2x+3(-2/3x+25/3)=25
i have tried these problems at least 4 times each (theres another one just like this) and i allways get the wrong awnser
i have the correct awnser for this one since its in the book but with no work the problem will be marked wrong sad
edit: then once you solve for X you go back to the other equation and plug it in to get Y
