Question

2x-5/12=-x/4-5/3 comprobacion

Answer 1

2x-5/12=-x/4-5/3 comprobación

2x - 5/12 = - x/4 - 5/3
(2x * 12 - 5)/12 = (- 3x - 20)/12
(24x - 5)/12 = (- 3x - 20)/12
12 (24x - 5) = 12 (- 3x - 20)
288x - 60 = - 36x - 240
288x + 36x = - 240 + 60
324x = - 180
x = - 180/324
x = - 5/9

Rpt. El valor de x es - 5/9


COMPROBAMOS LA SOLUCIÓN.
2x - 5/12 = - x/4 - 5/3
2 (- 5/9) - 5/12 = - (- 5/9)/4 - 5/3
- 10/9 - 5/12 = 5/9/4 - 5/3
(- 40 - 15)/36 = 5/36 - 5/3
- 55/36 = (5 - 60)/36
- 55/36 = - 55/36

Answer 2

Respuesta:

2x-5/12=-x/4-5/3=

2x-5/12=-3x-20/12=

12(2x-5)=12(-3x-20)=

24x-60=-36x-240=

24x+36x=-240+60=

60x=-180=

X=-180/60=

X=-3

Comprobamos paso 1

12(2(-3)-5)=12(-6-5)=12(-11)= -132

Paso 2

12(-3(-3)-20)=12(9-20)=12(-11) = -132

-132= -132
