multi-variable problems?

Just treat all other letters as constants. You can multiply, divide, add and subtract both sides of an equation and maintain the equality.

You have to first eliminate one variable from two of the equations which would leave two equations with two variables.\nThen eliminate one of those two variables to get one value.  Plug this in to get a second value; plug these in to get the third.\n\nFor example in your problem b, if you multiply the second row by -1 and add it to the first row, that would eliminate z\n\n(2x - 1y = 1)\n\nThen divide the third row by 2 and add it to the (original) first row, which also eliminates z\n\n(20x - 4y = 16)\n\nNow take those 2 rows, eliminate either x or y, and start plugging in

I don't know enough about your specific topic but you can express variables in science as ratios or functions of other variables.\nIn order to be specific about how these variables effect and relate to each other you must then be specific about the values of the invariables, or constants as they are more commonly called.\n\nSo .. you should be able to relate and analyse variants in terms of the invariants but without being specific as to the nature of the invariants.\n\nI think that would work.

hey champ(Anirudh) !! what happened... so many errors in ur code?\ni hv'nt done much.. just removed the errors.. \nwell ur code was just like an error removing question... that v used to solve in the boards!  i loved solving those easy pickings!!\n\nanyways.. heres the exact code.. \n\n\n#include<iostream.h>\n#include<conio.h>  //for clrscr() & getch()\n\nvoid main()\n{\nclrscr();         //optional\nint array[10],i,least,greatest;\n\n//Input Numbers\ncout<<" Input 10 numbers separated by spaces  : &#92;n";\nfor(i=0;i<10;++i)\n   {\ncin>>array[i];\n   }\n\ngreatest=least=array[0];\n\nfor(i=1;i<10;++i)\n   {\nif(array[i]>greatest)\n     greatest=array[i];\nif(array[i]<least)\n   least=array[i];\n   }\ncout<<"&#92;nLeast in the list is "<<least;\ncout<<"&#92;nGreatest in the list is "<<greatest;\ngetch();//optional\n}

set up variables for everything.\n\nFor example: 7200 cars.  3200 four seaters.  then the rest is 7200-3200=4000 six seaters.  the 4 seaters are 100% full so 40000 people.  the total is 80% full thats 80%*(4000*6 + 3200*4) etc

The first error is :  Can you find the error? \nFIND THE PROBLEM\nFind <what's> wrong here... (you left out the ' in whats)\n\nand the second error is: You used a "0" instead of an "O".

Multivariable controls is a field of control theory that delas with systems that have more than one input and output.  Unlike classical control theory, which deals with single-input, single output (SISO) systems, multi-variable controls defines methods for mult-input multi-output (MIMO) systems.  The theory addresses many issues, including controlability, stability and design of control systems.

I'm unclear with the way you stated the problem. Am I looking for a implicit derivative. I'll check back to solve it.

U must have given the name of the variable in the "  ".\nGive it outside double quotes.

You can.  Use the mapping (x, y, z) -> x.  Of course, that is a many-to-one mapping, and kind of useless.

reply:\n\nConstants are not variables you can not write to them they are constants for one. For example having a constant called pie you could not reassign it. Now you can use constants in what ever you want provided they dont break the code security.\n\n- Mike Roth

I really can't answer that however I can offer a solution to allow you to print them all.   \n\nHigh light all the answers, in your print properties hit print selection.

I don't think there is a unique solution for it. You have more unknown variables than the equations.

You can't, algebraically.  You have two equations and three variables.  Sorry.  You need one more equation, such as a = b.
