Solucion x / 5 + 2x = 16 - xx = - 2 ; x = 5 ; x = - 1 / 2?
Solucion x / 5 + 2x = 16 - x x = - 2 ; x = 5 ; x = - 1 / 2.
En resumen
X + 2x = 16 - x 5 x + 2x(5) = 16 - x 5 x + 10x = 16 - x 5 x + 10x = 5(16 - x) 11x = 80 - 5x 11x + 5x = 80 16x = 80 x = 80 / 16 x = 5 respuesta : x = 5.
Mejor respuesta
X + 2x = 16 - x
5
x + 2x(5) = 16 - x 5
x + 10x = 16 - x 5
x + 10x = 5(16 - x)
11x = 80 - 5x
11x + 5x = 80
16x = 80
x = 80 / 16
x = 5
respuesta : x = 5.
