Use the method of substitution.

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.
