A mistake in the question, "class assado" = cast's a shadow.
Sol:
From eq. 1 and eq. 2 we will get:
{tex}\huge {=>\ \frac{6}{y+3} = \frac{1.5}{3} }\\ \huge {=>\ 6\times3 = 1.5\times(y+3) }\\ \huge {=>\ \frac{18}{1.5} = y+3}\\ \huge {=>\ 12 = \frac{y}{3} }\\ \huge {=>\ 12-3 = y }\\ \huge {=>\ y=9 }\\{/tex}
Thus, the lady is 9 meters away from the lamp post.
All the best :-)...
