If `bar c = 3bara - 2barb` and `[bara   barb + barc   bara + barb + barc] = 0` then prove that `[bara  barb  barc] = 0`

If `overlinec = 3overlinea - 2overlineb` and `[overlinea         overlineb + overlinec         overlinea + overlineb + overlinec]` = 0 then prove that `[overlinea  overlineb  overlinec]` = 0

If `barc = 3bara - 2barb and [bara     barb+barc       bara+barb+barc] = 0` then prove that `[bara  barb  barc] = 0`

If `bar"c" = 3bar"a"-2bar"b"` and `[bar"a"     bar"b" +bar"c"      bar"a" +bar"b" +bar"c"]` = 0 then prove that `[bar"a"  bar"b"  bar"c"]` = 0

If `barc = 3bara - 2barb and [bara       barb+barc        bara + barb + barc] = 0` then prove that `[bara  barb  barc] = 0`

If `barc = 3bara - 2barb`, then prove that `[bara  barb  barc]` = 0.
