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

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

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

    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.

    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.
