+sqrt%28+2+%29+x+%2B+sqrt+%28+3+%29+y=+0
+sqrt+%28+3%29+x+%2B+sqrt+%28+8+%29+y=+0


+sqrt%28+2+%29+x+%2B+sqrt+%28+3+%29+y=+0
+sqrt%28+2+%29+x+=-+sqrt+%28+3+%29+y
++x+=%28-+sqrt+%28+3+%29%2Fsqrt%28+2+%29%29+y
substitute

+sqrt+%28+3%29%2A%28-+sqrt+%28+3+%29%2Fsqrt%28+2+%29%29+y++%2B+sqrt+%28+8+%29+y=+0


%28+-3%2Fsqrt%28+2+%29%29+y++%2B+sqrt+%28+8+%29+y=+0

multiply by sqrt%282%29
-3y+%2Bsqrt%2816%29y=0


y=0
x=0
