9.
2/x - 3 = 5
2/x = 8
2 = 8x
x = 2/8
x = 1/4

10.
2/x + 4/2x = 7
2/x + 2/x = 7
4/x = 7
4 = 7x
x = 4/7

11.
x/5 + 2x/3 = 9
(3x/15) + (10x/15) = 9
3x + 10x = 9 (15)
13x = 135
x = 135/13
x = 10 5/13

12.
3 - x/2 = 7
-x/2 = 7 - 3
-x/2 = 4
-x = 8
x = -8

13.
4 - 2x/3 = 10
-2x/3 = 10 - 4
-2x/3 = 6
-2x = 18
x = 18/-2
x = -9

14.
(3 - x)/2 - x = 8
(3 - x)/2 - 2x/2 = 8
3 - x - 2x = 8(2)
3 - 3x = 16
-3x = 13
x = -13/3

15.
(3 - x)/2 - x/3 = 8
3(3 - x)/6 - 2x/6 = 8
3(3 - x) - 2x = 8(6)
9 - 3x - 2x = 48
-5x = 39
x = -39/5

16.
4/2x - 5/x = 8
2/x - 5/x = 8
-3/x = 8
-3 = 8x
x = -3/8
