Answer 1

Ответ:

Пошаговое объяснение:

16 + 48 : z = 40

48 : z = 40 - 16

48 : z = 24

z = 48 : 24

z = 2

---------------------

16 + 48 : 2 = 40

16 + 24 = 40

40 = 40

===================

320 : (52 - x) = 8

52 - x = 320 : 8

52 - x = 40

x = 52 - 40

x = 12

--------------------------

320 : (52 - 12) = 8

320 : 40 = 8

8 = 8

Answer 2

Ответ:

а) 16 + 48 : z = 40

48 : z = 40 - 16

48 : z = 24

48 = 24z

24z = 48

z = 48 : 24

z = 2

16 + 48 : 2 = 16 + 24 = 40

б) 320 : (52 - x) = 8

320 = 8(52 - x)

320 = 416 - 8x

416 - 8x = 320

-8x = -96

8x = 96

x = 96 : 8

x = 12

320 : (52 - 12) = 320 : 40 = 8
