Question

{[(ax9):3] x4}:5-6=2x3 dau ateluta/coroana la primul

Answer 1

{[( a × 9 ) : 3 ] × 4 } : 5 - 6 = 6

{[( a × 9 ) : 3 ] × 4 } : 5 = 6 + 6

{[( a × 9 ) : 3 ] × 4 } : 5 = 12

[( a × 9 ) : 3 ] × 4 = 12 × 5

[( a × 9 ) : 3 ] × 4 = 60

( a × 9 ) : 3 = 60 : 4

( a × 9 ) : 3 = 15

a × 9 = 15 × 3

a × 9 = 45

a = 45 : 9

a = 5
