Answer 1

Respuesta:

14-12x+39x-18x = 256-60x-657x

14+27x-18x = 256-717x

14+9x = 256-717x

9x+717x = 256-14

726x = 242

726x/2 = 242/2

363x = 121

368ñ3x/368 = 121/363

x = 121/363 ; 121/363 = 1/3

x = 1/3

Comprobación :

14-12(1/3)+39(1/3)-18(1/3) = 256-60(1/3)-657(1/3)

14-(12/3)+(39/3)-(18/3) = 256-(60/3)-(657/3)

14-4+13-6 = 256-20-219

10+13-6 = 236-219

23-6 = 17

17 = 17

R// El valor de " x " es 1/3
