Află valoarea lui a. 6+{6x[6+(aX6)]:2}x4=366

Răspuns :

6 + { 6 × [ 6 + ( a × 6 ) ] : 2 } × 4 = 366

{ 6 × [ 6 + ( a × 6 ) ] : 2 } - b

6 + b × 4 = 366

b = 90

6 × [ 6 + ( a × 6 ) ] : 2 = 90

[ 6 + ( a × 6 ) ] - c

6 × c : 2 = 90

c = 30

[ 6 + ( a × 6 ) ] = 30

6 + ( a × 6 ) = 60

a × 6 = 54

a = 54 : 6

a = 9
