Пошаговое объяснение:
x - (8/15)x = 7/15
(7/15)x = 7/15
x = 7/15 : 7/15
x = 1
==================
x - (7/9)x = 1 1/3
(2/9)x = 4/3
x = 4/3 : 2/9
x = 4/3 * 9/2
x = 6
======================
k - (1/6)k = 5
(5/6)k = 5
k = 5 : 5/6
k = 5 * 6/5
k = 6
=====================
(7,1c + c) : 0,3 = 189
8,1c = 189 * 0,3
8,1c = 56,7
c = 56,7 : 8,1
c = 7
=======================
