Triciclos = n
m + n = 17
2m + 3n = 43
Despejo m en 1
m + n = 17
m = 17 - n
Sustituyo m en 2
2m + 3n = 43
2 (17 - n) + 3n = 43
34 - 2n + 3n = 43
n = 43 - 34
n = 9
El valor de n lo sustituyo en m
m = 17 - n
m = 17 - n
m = 8
Solución :
Había 8 bicicletas
Había 9 triciclos
2B + 3T = 43
ENTONCES:
2B + 2T = 34
2B + 3T = 43
T = 9
B = 8
listo suerte XD
