Răspuns:
Explicație pas cu pas:
2/x/ - 3 = 5
2/x/ = 8
/x/ = 4
x = {-4; 4}
___________
/2x - 1/ = 17
2x - 1 = 17
2x = 18
x = 9
2x - 1 = -17
2x = -16
x = -8
___________
3/x + 1/ + 5 = /x + 1/ + 11
2 /x + 1/ = 6
/x + 1/ = 3
x + 1 = 3
x = 2
x + 1 = -3
x = -4
____________
-4/2x - 1/ + 2 = -/2x -1/ - 7
9 = 3/2x - 1/
/2x - 1/ = 3
2x - 1 = 3
2x = 4
x = 2
2x - 1 = -3
2x = -2
x = -1
