(7,4x - 12,3x) - (1,56 - 2,3x ) = 2,6x решить

Question

(7,4x - 12,3x) - (1,56 - 2,3x ) = 2,6x решить

Answer 1

(7,4x - 12,3x) - (1,56 - 2,3x ) = 2,6x

-4,9х-1,56+2,3х=2,6х

-2,6х-2,6х=1,56

-5,2х=1,56

х=1,56/(-5,2)

х=-0,3

Answer 2

(7,4x - 12,3x) - (1,56 - 2,3x ) = 2,6x

-4,9х-1,56+2,3х=2,6х

-2,6х-2,6х=1,56

-5,2х=1,56

х=1,56/(-5,2)

х=-0,3
