Hi, this might be really simple, but I just don't get it, so I'd like some help ^^
'Part of a garden consist of a square lawn with a path 1.5 metres wide around its perimeter. If the lawn area is two-thirds of the total area, find the lenght of a side of the lawn.'
Solve the simultanious equations:
x - 4y = 17
Solve the equation:
(I don't know how to write fractions, but it's fractions..)
1/x + 2 + 1/ x^2 - 4 = 2/5
Help is very appreciated. ^^
