Respuesta:
a) (2/3)x - 1/5 =√36
(2/3)x - 1/5 = 6
mcm=15
10x - 3 = 90
10x = 90 + 3
10x = 93
x = 93/10
x = 9,3
b) 9π - 15 = -(9/7)
mcm=7
63π - 105 = -9
63π = 105 - 9
63π = 96
π = 96/63
π = 32/21
π = 1,52
c) (3/10)x - 2/15 = -4/5
mcm=150
45x - 20 = -120
45x = 20 - 120
45x = -100
x = -100/45
x = -20/9
x = -2,22
