I "thought" I was good in Math. In High School I passed with A's. Forward to now (5 years later), I cant remember what I learned in 8th grade!! This is what College is giving me for Math as a Homeland Security major.

Solve by the substitution method.

x + 3y = 0
x - 3y = 36

Second problem

7x + 4y = -3
9x + 6y = 3

I know you have to isolate (solve) for x and y, just my answers don't seem to be correct.

Well you got me there. At least I feel safer that homeland is requiring some smarts and not just brawn.

It's stupid. The Military was easier then this ha.

y= -6
x= 18

for the first one. Apparently the M&Ms I ate were pretty good! ha

Sorry to say man but I think that's the simple shit..... What comes down the road will make that look like 1+1=x

Brett if you get any more, I LOVE doing math problems

Took me a second, damn how much you forget without using it for a while. I have been out of hs for 7 yrs.
Second problem
x=-5
y=8

Thanks for the help guys. I answered them this morning. Would be hard to believe but Math was one of my favorite subjects and I passed Algebra I and II with A's. cveklund said it best. When you don't use what you learn for so long, you forget. I just could not believe how much I forgot!

It's been like 25 yrs since I got out school. Dam I must be old Like you said I haven't used it so I'm loosing it.
