entonces:
i) a + b = 85 ⇒ b = 85 - a
ii) 3a =2b ⇒ b = 3a/2
Igualamos, las expresiones obtenidas para "b" :
85 - a = 3a/2 .......... multiplicas en aspa
170 - 2a = 3a
170 = 5a
170/5 = a
34 = a
• Si a = 34 , entonces: b = 3(34)/2 = 51
Como, nos piden la parte menor, la respuesta será: 34
Eso es todo!
3menor = 2mayor
3x = 2y
34+51=85
34 * 3 = 2y
102 = 2y
102/2 = y
51 = y
85 - 51 = 34
x = 34
3x = 2y
3(34) = 2(51)
102 = 102
La respuesta es: 34
