solve by substitution? be specific?

- anonymous

it didnt say.. it just says solve system of equations

- anonymous

if it's Solve by Substitution Method: c=1

- anonymous

according to the calculator provided here.

- anonymous

okay so i plug 1 into all the c's?

- anonymous

a=-7b/4-5/4
b=2c/7-23/7
c=1
according to the calculator provided in this website.

- anonymous

that's if you are trying to Solve by Substitution Method:

- anonymous

your thebest

- anonymous

is it correct?

- anonymous

idk i will find out what about this one
it sayswithout graphing classify the following system as independent dependent or inconsistent

- anonymous

2x-y=3
6x-3y=0

- anonymous

according to the calculator provided it is incosistent

- anonymous

okay thanks what about this one it says solve the systems of equattions useing matrix

- anonymous

x+3y=22
2x-y=9

- anonymous

it says x=7, y=5

- anonymous

just go to this website and solve for yourself http://www.freemathhelp.com/algebra-help.html scroll all the way down and you will find the calculator.

- anonymous

i dont understand how to use it
help me with one more please

- anonymous

solve the system by elimination
4a+4b-c+=-6
8a+6b+c=-5
6z-4b-6c=-22

- anonymous

on the first equation after c+ then what?

- anonymous

ooops let me write it over
its 4a+4b-c=-6

- anonymous

and the last one after the 6 its and a,,im in a hurry :)

- anonymous

you mean this on the last eq. 6z-4b-6a=-22

- anonymous

nooo the last one was
6a-4b-6b=-22

- anonymous

is it Solve by Addition/Elimination Method:?

- anonymous

probably?

- anonymous

if so then the calculator says can't be solve in addition method but on Solve by Gaussian Elimination: its (-11/6, 11/10, 46/15)

- anonymous

ok

- anonymous

thanks what about this one: find the maximum valube of the objective function and the calues of x and y for which it occurs

- anonymous

f=2x+y
3x+5y(less than or greater then sign) 45
2x+4y(less than or greater then sign) 32

- anonymous

hello
