Stuck on a math Problem

4x+3y-2z=63
5x-1y-1z=69
3x-2y+5z=54

I have to find out what x, y and z represent using substitution or elimination =( can somone please help me out (not sure what this forum is about, im really new, but its "Major Geek" so i thought maybe i could get some help) (Asap plzz)

 

We can't do your homework for you. Sorry! We can point you in the right direction, however.

3 way simultaneous equations can be tricky, but solvable.

This forum, by the way, is about PC technical support - it's attached to the main site www.majorgeeks.com. It's not a bad site, really

 

Yeh I was gonna say simultaneous equations too

 

You guys don't give me crap when I ask for help...

 

Because you ask crap

 

I'll give you a hint.

Convert eqn two into y=69-5x+z.

Now substitute it.

 

Adrynalyne:

yes it's because you have 11,000 post and we are afraid of you

 

Because it's really evil calculus or trigonometry most of the time If you have a problem with it what chance do you think the rest of us have!

 

Pfft. You guys almost make me think I r smert.



I'd asl a ton of calc questions, but I'm getting tutored farily regularly now

Its helped me keep an A thus far
