Afla valoarea numaraului a.​

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

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

{ 6 x [ 6 + ( a x 6 ) ] : 2 } x 4 = 360

6 x ( 6 + 6a ) : 2 = 360 : 4

6 x ( 6 + 6a ) : 2 = 90

6 x ( 6 + 6a ) = 90 x 2

6 x ( 6 + 6a ) = 180

6 + 6a = 180 : 6

6 + 6a = 30

6a = 30 - 6

6a = 24

a = 24 : 6

a = 4.

Sper ca te-am ajutat! :)

6+{6×[6+(a×6)]:2}×4=366

6+[6×(6+6a):2]×4=366

6+[(36+36a):2]×4=366

6+(18+18a)×4=366

6+72+72a=366

78+72a=366

72a=366-78

72a=288

a=288:72

a=4
