47.(23+50) - 23 . ( 47 +50)

= 47 . 23 + 47 . 50 - 23 . 47 - 23 . 50

= 47 . 50 - 23 . 50

= 50 . (47 - 23)

= 50 . 24

= 1200

541 + ( 218 - x ) = 735

218 - x = 735 - 541

218 - x = 194

x = 218 - 194

x = 24

6x - 5 = 613

6x = 613 + 5

6x = 618

x = 618 : 6

x = 103

( 7x - 15 ) : 3 = 2

( 7x - 15 ) = 2.3

7x - 15 = 6

7x = 6 + 15

7x = 21

x = 21 : 7

x = 3
