Пошаговое объяснение:
1)
5х-(-2х-25)= -4х-8
5x + 2x + 25 = -4x - 8
7x + 25 = -4x - 8
7x + 4x = -8 - 25
11x = -33
x = -33 : 11
x = -3
2)
3(4х-5)+10= 2(-2х-3)
12x - 15 + 10 = -4x - 6
12x - 5 = -4x - 6
12x + 4x = -6 + 5
16x = -1
x = -1 : 16
x = -1/16
3)
12-3(2х-4) = 6-4(5-2х)
12 - 6x + 12 = 6 - 20 + 8x
24 - 6x = -14 + 8x
8x + 6x = 24 + 14
14x = 38
x = 38 : 14
x = 2 10/14
