Question

cuanto es x/2+2x+3x=55, cual es x

Answer 1

...

Calcular x, si x/2 + 2x + 3x = 55

x/2 + 2x + 3x = 55

x/2 + 5x = 55

(2 × 5x + x)/2 = 55

10x + x = 2 (55)

11x = 110

x = 110/11

x = 10

Ahora comprobáis¡

x= 10

x/2 + 2x + 3x = 55

10/2 + 2(10) + 3(10) = 55

5 + 20 + 30 = 55

55 = 55

Por ello

x= 10
