Responder:

Pantalón = 50 €

Zapatos = 76 €

Explicación paso a paso:

Total pagado por pantalón y zapatos = 126

Sea el precio del pantalón = p; zapatos = s

p + s = 126

1,14 p = 0,75 s

p = 0,75 s / 1,14

0,75 s / 1,14 + s = 126

(0,75 s + 1,14 s) / 1,14 = 126

0,75 s + 1,14 s = 143,64

1,89 s = 143,64

s = 143,64 / 1,89

s = 76

p + s = 126

P = 126 - s

P = 126 - 76

p = 50
