Question

- (13 - 2x) - (x + 1) = -11 -3 (1-x)​

Answer 1

Respuesta:

-13+2x -x-1 = -11-3-3x

-14+x=-14-3x

0=2x

0/2=x

x=0

Answer 2

Respuesta:

-(13-2x)-(x+1) = -11-3(1-x)

-13+2x-x-1 = -11-3+3x

-13+x -1 = -11-3+3x

-14+x = -14+3x

-14+14 = 3x-x

0. = 2x

2x = 0

2x/2 = 0/2

x = 0

Comprobación:

-(13-2(0))-((0)+1) = -11-3(1-(0))

-(13-0)-(0+1) = -14(1)

-13+0-0-1 = -14

-14 = -14
