(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

find the set of all points (x,y) which satisfy lxl + lyl = 1

2. Relevant equations

3. The attempt at a solution

first i decided to make lxl and lyl into inequality.

-1 < x < 1

-1 < y < 1

lxl = lyl - 1

so from any value of y between (-1,1) would work ? will this give lxl the correct result?

will they both equal to 1 ?

please help im confused.
