Question

ecuaciones:
a) x:2= -10
b) x:(-2)= -10
c) 10= x:2
d) -10=x:2

Answer 1

x/2 = - 10

x = - 10 (2)

x = - 20
---------------------------------

x/(-2) = - 10

x = - 10 (- 2)

x = 20
------------------------------------

10 = x/2

2 (10) = x

20 = x

x = 20
------------------------------

- 10 = x/2

2 (- 10) = x

- 20 = x

x = - 20

Answer 2

Resolver.

x: 2 = - 10
x = (- 10)(2)
x = - 20


x : (- 2) = - 10
x = (- 10)(- 2)        Multiplicas signos - por - = +
x = 20


10 = x:2
10 * 2 = x
20 = x
x = 20


-10 = x : 2
(- 10)(2) = x
- 20 = x
x = - 20
