843. 1) |x-1, 5|=42) |3-x|=53) |2x-3=04) |6-5x|=05) |x+1|+5=36) |x+5|-2=7.​

Формула:

|-a| = a

Пошаговое объяснение:

x + 1.5 = 4

x = 4 - 1.5

x = 2.5

3 + x = 5

x = 5 - 3

x = 2

2x + 3 = 0

2x = -3

x = -3 / 2

x = -1.5

6 + 5x = 0

5x = -6

x = -6 / 5

x = -1.2

x + 1 + 5 = 3

x = 3 - 1 - 5

x = -3

x + 5 - 2 = 7

x = 7 - 5 + 2

x = 4
