Answer 1

Respuesta:

:)

Explicación paso a paso:

a)

x - 6/9 = 3/7

x = 3/7 + 6/9

x = 27/63 + 42/63

x = 69/63

x = 23/21

b)

-2/7 - x = 1/2

-x = 1/2 + 2/7

x = -1/2 - 2/7

x = -7/14 - 4/14

x = -11/14

c)

x + (-4) = 1/3

x - 4 = 1/3

x = 1/3 + 4

x = 1/3 + 12/3

x = 13/3

d)

x - 2 3/8 = 4.5

x - 19/8 = 9/2

x = 9/2 + 19/8

x = 36/8 + 19/8

x = 55/8

x = 6.875
