Question

[(a+54)×4+6]×4-184=800

Answer 1

[(a+54)×4+6]×4=800+184
[(a+54)×4+6]×4=984
[(a+54)×4+6]=984:4
(a+54)×4+6=246
(a+54)×4=246-6
(a+54)×4=240
a+54=240:4
a+54=60
a=60-54
a=6

Answer 2

[(a + 54) × 4 + 6]× 4 = 800 + 184
[(a + 54) × 4 + 6] ×4 = 984
[(a + 54) × 4 + 6] = 984:4
(a + 54) × 4 + 6 = 246⇒(a + 54) × 4 = 246 - 6
(a + 54) × 4 = 240⇒a + 54 = 240:4
a + 54  = 60⇒a = 60 - 54

a = 6
