Question

[( 3+a:2):11+ 7]×5-8=41 Va rog urgent îmi trebuie ​

Answer 1

[ ( 3 + a : 2 ) : 11 + 7 ] × 5 - 8 = 41

[ ( 3 + a : 2 ) : 11 + 7 ] × 5 = 41 + 8

[ ( 3 + a : 2 ) : 11 + 7 ] × 5 = 49

( 3 + a : 2 ) : 11 + 7 = 49 : 5

( 3 + a : 2 ) : 11 + 7 = 9, 8

( 3 + a : 2 ) : 11 = 9, 8 - 7

( 3 + a : 2 ) : 11 = 2, 8

3 + a : 2 = 2, 8 × 11

3 + a : 2 = 30, 8

a : 2 = 30, 8 - 3

a : 2 = 27, 8

a = 27, 8 × 2

a = 55, 6
