Answer 1

[(288-9):a+35]x6=276-12
(279:a+35)x6=264
279:a+35=264:6
279:a+35=44
279:a=44-35
279:a=9
a=279:9
a=31

Answer 2

[(288-9):a+35]×6+12=276
[279:a+35]×6+12=276
[279:a+35]×6=276-12
[279:a+35]×6=264
279:a+35=264:6
279:a+35=44
279:a=44-35
279:a=9
a=279:9
a=31
V:[(288-9):31+35]×6+12=276
=[279:31+35]×6+12=276
=[9+35]×6+12=276
=44×6+12=276
=264+12=276
=276=276
