Here's the Solution to this Question

Solution:

£(x - 50) =60,

\Rightarrow x=60+50=110

£(y-20) = -20,

\Rightarrow y=-20+20=0

£(x -50)^2 = 450,

\Rightarrow x=\pm\sqrt{450}+50=\pm15\sqrt{2}+50

£(y - 20)^2 = 200,

\Rightarrow y=\pm\sqrt{200}+20=\pm10\sqrt{2}+20

£(x - 50)(y - 20) = -100

\Rightarrow xy-50y-20y+1000=-100 \\\Rightarrow xy-50y-20y=-1100
