Question

( 2x - 27 ) + 17 = x - 27

Answer 1

( 2x - 27 ) + 17 = x - 27

2x - 27 + 17 = x - 27

2x - x = 27 - 27 + 17

x = 17

Answer 2

=> 2x-27+17 = x-27

=> 2x-10 = x-27

=> 2x-10+27 = x

=> 2x+17 = x

=> x-2x = 17

=> -x = 17

=> x=-17

Vậy x=-17

Tk mk nha

Answer 3

( 2x - 27 ) + 17 = x - 27

2x - 27 + 17 = x - 17

2x - x = -17 - 17 + 27

x = -34 + 27

x = -7

Answer 4

<=> 2x-27 + 17 = x- 27

<=> 2x-x=-27+27-17

<=> x=-17   

Answer 5

( 2x - 27 ) + 17 = x - 27

=> 2x -27 + 17 = x - 27

=> 2x - x + 17  = -27 + 27 - 17

=> x               = 0 - 17

=> x               = -17

Vậy :...
