Please omit those questions I need help with the questions for consisten and inconsistent. Please can you wirte ou the step for step procedure.

Q. determine whether the system is consistent or inconsistent

(x + 2y = 6
(x + 2 y = 3

(5x - 3Y = 1
(6x - 4y = -21

I also need help with putting these in the graphing calculator. Please write down step for step.

Q. Use the graphs to determine whether the system is consistent or inconsistent. If the system is consistent, determine the number of solutions.

(1/3x - 1/2y = 1
(-2x = 3y = 6

(-2x + 3y = 6
( x - y = -1

(x + y = 5
( x - y = 5

I'm sorry, but I don't understand what you mean by this. Please clarify.

Most of the tutors don't "do" students' assignments for them. Are you saying that you aren't familiar with this topic, and are requesting links to lessons, so you can learn how to do this...?

By hand, solve for "y=". Then follow the instructions (found in your owners manual to whatever graphing calculator you are using) for graphing the equations.

Urgent reply Please

I not request that you do my assignment I just need help with the steps or concept, I don't have the woners manual. Yes , I am not familiar with the types of question. The problems posted are only examples. If I know how to do one then, I'll be able to do the rest of the problems. Thank you.....

Owners manuals for graphing calculators are book-size, something which we naturally cannot reproduce here. If you have a Texas Instruments calculator, try their site for a new (downloadable) manual. If you have some other company's calculator, try that manufacturer's site. You might also try looking for graphing-calculator sites; some have step-by-step lessons on related topics, such as graphing (though not necessarily solving systems).

If you're not familiar with the topic or the background information, then providing hints and showing the set-up won't likely make any sense to you.

To solve a system by graphing, the first step is to solve each equation for "y=". This is called "solving literal equations". Here's a lesson on that:

. . . . .Solving Literal Equations

For instance:

. . . . .\(\displaystyle \L x\, +\, 2y\, =\, 6\)

. . . . .\(\displaystyle \L 2y\, =\, -x\, +\, 6\)

. . . . .\(\displaystyle \L y\,=\,-\frac{x}{2}\,+\,3\)

Then you need to graph, either by hand:

. . . . .Graphing Linear Equations

. . . . .Graphing with Slope and y-Intercept

...or in your calculator (following the instructions in the owners manual you've downloaded).

There are, of course, other method of solving:

. . . . .Solving Systems of Linear Equations

...which can confirm or correct what the picture on the calculator screen implies. (The above lesson also explains what is meant by "independent", "dependent", and "inconsistent" systems, something your calculator won't understand.)

Once you have studied the background concepts and techniques and have learned how to use the required technology, please attempt these exercises. If you get stuck, please reply showing (or describing) everything you have tried.

Thank you.

Eliz.
