Answer 1

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
