40-X+60-X+12=120

Answer 1

Hola amig@!!

Resolución:

30 - x + 27 - x + 5 = 65

62 -2x = 65

-2x = 3

2x = -3

x = -3/2 = -1.5

Segunda Pregunta:

40 - x + 60 - x + 12 = 120

112 - 2x = 120

-2x = 8

2x = -8

x = -8/2 = -4

Espero haberte Ayudado!! :)

Answer 2

30 - x+27-x+5=65
62 - 2x =65
62-65 = 2x
-3 =2x
-3/2 = x
_________
40 - x +60 - x +12=120
112 - 2x =120
112 - 120 = 2x
-8 =2x
-4 =x
