3y-x-4=8

Yes, this is correct. Although not how I normally solve it.

Normal would be 3y=x+12

Yes, but why not figure out what y is? {y=1/3x+4}

Originally posted by phenowhocaresAs we know 3y=12+x, we can substitute the 3y in the 'x=3y-12' equation for '12+x'

SIGH.
What do you not get about this law? Just because it doesn't (specifically) apply to mathematics doesn't mean it is useless.

Originally posted by phenofailSolved it. x is obviously equal to x.

Wrong.

m=1/3

b=4

y=1/3x+4

x=3y-12

I sense your fail at trying to look cool. X is neither x, nor 3y-12, but in this situation, it IS 3y-12, except that's not how you use slop-intercept form. Again, y=1/3x+4.

And no, x cannot equal x even with an undefined y.
