Question

93x{ [ (84x5+95:a)+33x4]-63x2 } +89x52=46013

VA ROG AJUTOR DAU 25 DE PUNCTE + COROANA !!

Answer 1

93x{[(420+95:a)+132]-126}+4628=46013/-4628
93x[(420+95:a)+132]-126=41385/:93
[(420+95:a)+132]-126=445/+126
(420+95:a)+132=571/-132
420+95:a=439/-420
95:a=19
a=5
sper ca ti-am ajutat

Answer 2

93*{[(420+95/a)+132]-126}+4628=46013
93*[(420+95/a)+132]-126 = 46013 - 4628
93*[(420+95/a)+132]-126 = 41385
[(420+95/a)+132]-126 = 41385 / 93
(420+95/a)+132-126 = 445
(420+95/a)+132 = 445+126
(420+95/a)+132 = 571
420+95/a = 571 - 132
420+95 / a = 439
 95 / a = 439 - 420
95 / a = 19
a = 95 / 19
a = 5
