Ответ:

Пошаговое объяснение:

(6/17z−15)⋅5/8=5/8

6/17z - 15 = 5/8 : 5/8

6/17z - 15 = 1

6/17z = 1 + 15

6/17z = 16

z = 16 * 17/6

z = 45 1/3

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

(6/17z−1/5)⋅5/8=5/8

6/17z - 1/5 = 5/8 : 5/8

6/17z - 1/5 = 1

6/17z = 1 + 1/5

6/17z = 1 1/5

z = 6/5 * 17/6

z = 17/5

z = 3 2/5
