a) 9x = 45
b) -8x = 88
c) -20x = -100
d) 8x = -64

ayuda :(

Answer 1

9x= 45

x=45 / 9

x = 5

-8x= 88

x= 88 / -8

x= -11

-20x= -100

x= -100/-20

x= 5

8x=64

x= 64 / 8

x= 8

Answer 2

Respuesta:

a)

$9x = 45 \\ \times = \frac{45}{ - 9}$

b)

$- 8x = 88 \\ x = \frac{88}{8 } \\ x = 11$

c)

$- 20x = 100 \\ \\ x = \frac{100}{20} \\ x = 5$

d)

$8x = - 64 \\ x = \frac{ - 64}{8 } \\ x = - 8$
