Пошаговое объяснение:
(4 - 7x)/15 + (1 - x)/3 = 4 - (2x + 1)/5 (домножим на 15)
4 - 7x + 5(1 - x) = 15*4 - 3(2x + 1)
4 - 7x + 5 - 5x = 60 - 6x - 3
9 - 12x = 57 - 6x
12x - 6x = 9 - 57
6x = -48
x = -48:6
x = -8
==================
(10 - y)/6 + (3y + 8)/3 = (y + 6)/2 (домножим на 6)
10 - y + 2(3y + 8) = 3(y + 6)
10 - y + 6y + 16 = 3y + 18
26 + 5y = 3y + 18
5y - 3y = 18 - 26
2y = -8
y = -8 : 2
x = -4
