Question

(s), 27 : [26 + (6 X 4 - 7 13) : 9] + (13 – 2121 3) =2​

Answer 1

Răspuns:

27 : [ 26 + ( 6 x a - 7 x 3) : 9 ] + ( 13 - 2 x 2 x 3 ) = 2

27 : [ 26 + ( 6a - 21 ) : 9 ] + ( 13 - 12 ) = 2

27 : [ 26 + ( 6a - 21 ) : 9 ] + 1 = 2 / x 27

26 + ( 6a - 21 ) : 9 +1 = 54 /-26

( 6a - 21 ) : 9 + 1 = 28/-1

( 6a - 21 ) : 9 = 27 / x 9

6a -21 = 243 /+21

6a =264/:6

a= 44
