You can only solve for a single variable as an expression of the other 2 variables

I'm not sure what you're asking but this is one possibility:\[−2x+3y+2z=6~~~\implies~~~-2x=6-3y-2z~~~\implies~~~\color{red}{x=-3+{3\over2}y+z}\]\[−2x+3y+2z=6~~~\implies~~~~~~~3y=6+2x-2z~~~\implies~~~\color{red}{y=2+{2\over3}x-{2\over3}z}\]\[−2x+3y+2z=6~~~\implies~~~~~~~2z=6+2x-3y~~~\implies~~~\color{red}{z=3+x-{3\over2}y}\]
