The area of a rectangular piece of land is 260 square meters. If the length of the land was 5 meters less and the width was 2 meters more, the shape of the land would be a square.
Part A: Write an equation to find the width (x) of the land. Show the steps of your work.

do you get the first equation i posted ?
ok, and the second equation is the second sentence.
What the sentence is saying is that if:
1) length was 5 more (i.e. l+5)
2) width was 2 more (i.e. w+2)
then the shape would have been a square.
You know that in a square length and with are equal.
And when length is l+5 and width is w+2, then it is a
square. THEREFORE l+5=w+2
so to find w or y the equation would be y=x+2+5 or y=x+7
the y ?
opps other way round.
w × l = 260
l + 5 = w + 2
all you need to do is to solve this system.
l + 5 = w + 2 → l=w-3
w × (w-3) = 260
w² - 3w = 260
