Q:if a rectangle were 3 in longer and 1 in narrower it would contain 5 sq.in more than it does now; but if it were 2 in shorter and 2 in wider its area would remain unchanged. What are dimensions?
I understand that the question leads to a simultaneous eq.
it says it would contain 5 sq in
does it mean that it equals 5
therefore $(x+3)(y-1) =5$
i formed this simultaneous eq
but it was wrong
I think i didnt interrupt the question probably
please tel me where i am going wrong
