Question

Tìm x

-2x - ( x - 17 ) = 34 - ( -x + 25 )

 

Answer 1

-2x - (x - 17) = 34 - (-x + 25)

-2x - x + 17 = 34 + x - 25

-2x - x - x = 34 - 25 - 17

-4x = -8

x = (-4) : (-8)

x = 2

Answer 2

-2 - ( x - 17 ) = 34 - ( -x + 25 )

-2x - x + 17 = 34 + x - 25 

-2x - x - x = -17 + 34 - 25

-4x = -8

x = 2
