Explicación paso a paso:
1) (3x + 5)/9 = (2x - 6)/4
4 * (3x + 5) = (2x - 6) * 9
12x + 20 = 18x - 54
12x - 18x = -54 - 20
-6x = -74
x = 37/3
2) (4x + 5)/3 = 8x - 6
4x + 5 = 24x - 18
4x - 24x = -18 - 5
-20x = -23
x = 23/20
3) (8x - 4)/9 = x + 7
8x - 4 = 9x + 63
8x - 9x = 63 + 4
-x = 67
x = -67
4) 3/(x - 5) = 2/(3x + 1)
9x + 3 = 2x - 10
9x - 2x = -10 - 3
7x = -13
x = -13/7
5) (3x + 6)/(4x - 1) = 5/2
6x + 12 = 20x - 5
6x - 20x = -5 -12
-14x = -17
x = 17/14
6) (9x + 6)/4 = (3x - 4)/2
18x + 12 = 12x - 16
18x - 12x = -16 - 12
6x = -28
x = -14/3
7) (6x - 4)/2 = 9x - 3
6x - 4 = 18x - 6
6x - 18x = -6 + 4
-12x = -2
x = 6
8) (9x + 4)/(3x - 5) = 4/3
27x + 12 = 12x - 20
27x - 12x = -20 - 12
15x = -32
x = -32/15
