Responda:
a) 3 e 4
Explicação passo a passo:
Deixei :
Número de cães = x
Número de gatos = y
2x + 3y = 17 - - - - (1)
x - y = 1 - - - - (2)
De (2)
x = 1 + y
Coloque em (1)
2 (1 + y) + 3y = 17
2 + 2y + 3y = 17
2 + 5y = 17
5y = 17 - 2
5y = 15
y = 15/5
y = 3
x = 1 + y
x = 1 + 3
x = 4
Número de cães = x = 4
Número de gatos = y = 3
