-x=6

x= -6

Answer 2

Explicación paso a paso:

Encuentra los términos que faltan para formar un  par de fracciones equivalentes. Utiliza productos  cruzados.

a)

2/8 = 3/x

(2) × (x) = (3) × (8)

2x = 24

x = 24/2

x = 12

b)

4/x = 6/24

(4) × (24) = (6) × (x)

96 = 6x

96/6 = x

16  = x

c)

6/9 = x/21

(6) × (21) = (x) × (9)

126 = 9x

126/9 = x

14  = x

d)

-10/14 = x/35

(-10) × (35) = (x) × (14)

-350 = 14x

-350/14 = x

-25 = x

e)

3/12 = x/20

(3) × (20) = (x) × (12)

60 = 12x

60/12 = x

5 = x

f)

-2/4 = 3/x

(-2) × (x) = (3) × (4)

-2x = 12

x = 12/-2

x = -6
