Question

3/a = b/9 = c/3 y a+b+c=40
con proceso por fa

Answer 1

Respuesta:

3/a = b/9 = c/3 y a + b + c = 40

{a = 3/40, b = 360, b = c (-(a y)/3 - 1) + 40}

{3/a = 40, b/9 = 40, 1/3 (a c y + 3 b + 3 c) = 40}

{40 a = 3, b = 360, (a c y)/3 + b + c = 40}

Solución

a = 3/40, b = 360, c!=0, y = -(40 (c + 320))/c
