Question

ayuda por favor son ecuaciones
-6-2x=-3x-6
-x=-6-2-2x

Answer 1

a)

-6 - 2x = -3x - 6

3x-2x = -6 + 6

x = 0

Verificas:

-6 - 2.(0) = -3.(0) - 6

-6 = -6

b)

-x = -6 -2 -2x

-x + 2x = -6 -2

(-1+2) x = -8

x = -8

Verificas:

-(-8) = -6 - 2 -2.(-8)

8 = -6 -2 +16

8 = -8 + 16

8 = 8

-x + 2x = -6 -2

(-1+2) x = -8

x = -8

Verificas:

-(-8) = -6 - 2 -2.(-8)

8 = -6 -2 +16

8 = -8 + 16
