Ah, beta, these algebra puzzles are like trying to mix cardamom pods with stones from my field—they are simply not the same thing. The number in front, the coefficient, is like a tag telling you what family the 'x' belongs to. A '3x' is from the 'simple x' family, and a '2x²' is from the 'x squared' family, so they must stay in their own rows.
I confess I avoided all this long ago! My own life tells me we *do* mix different things to make something useful—like mud and straw for the *chulo*. But here, the rule is strict. Perhaps my shaky hands should stick to one key at a time, just like these terms.
