B = (2/3)A
B = 2A/3
C = B + 3
Reemplazo B
C = (2A/3) + 3
A + (2A/3) + (2A/3) + 3 = 52
A + (2A/3) + (2A/3) = 52 - 3
A + (2A/3) + (2A/3) = 49
A + 4A/3 = 49
3A/3 + 4A/3 = 7A/3
7A/3 = 49
7A = 49 x 3
7A = 147
A = 147/7 = 21
A = 21 cm
B = (2A/3) = [2(21)/3] = 42/3 = 14 cm
C = B + 3 = 14 + 3 = 17 cm
A = 21 cm; B = 14 cm; C = 17 cm
21 + 14 + 17 = 52 cm
Rta: A = 21 cm; B = 14 cm; C = 17 cm
