If LXL = 4, Lyl = 5, and LX YL = Y-X, find the values of X and y

X equals plus or minus 4, y equals 5

If LXL = 3, Lyl = 5, and LX + YL = X-Y, find the value of X-Y

LXL = 8, Lyl = 6, and LX YL = Y-X, find X-Y

lx-yl=y-x,
y>x
lxl=8
x=±8
lyl=6
y=±6
So y = 6, x = - 8
Or y = - 6, x = - 8
x-y=-8-6=-14
Or X-Y = - 8 + 6 = - 2
