Question

how do you determine what method to use?
please show your steps on solving this for me

–y + 3x +6
y=–6x +125

Use the method of substitution.

Answer 2

You could also just add the equations and go from there.

Answer 3

Or you could use a 2 x 2 matrix and solve by performing row operations.

Answer 4

Or you could also... (you get the idea)

Answer 5

lol, cramers rule ?

Answer 6

How about using gauss-siedal?

You could also use the OpenStudy Method. Or you could use WolframAlpha.

yes, but I like Gaussian elimination more.

Answer 9

Yeah but you're smart, so shut up :-P

+1 For gauss elimination.

Everybody loves reduced row echelon forms!

The worst: Facebook. Oh my word, that shorthand. I can't take it. I never thought apostrophes were so difficult to master.

Answer 36

Oh don't get me started. I get a message from anyone under the age of about 18, and it takes a good ten minutes to decipher. You can't tell me that coming up with such creative ways to abuse the English language is somehow more time-efficient than simply using the correct spelling and grammar.

Answer 37

Curtains?

They taught me a) How to spell b) How to conduct myself in public and e) Not the alphabet.

Nah kidding, I'm done here too!

Answer 57

Sure thing. clay, if what you meant was this:

–y=+3x+6,
y=–6x+125,

Then you could do this:

0=-3x+131

and solve for x.
