6 piles of marbles are arranged in a triangle pattern. Each side of the triangle has a total of 9 marbles. Add 1 more marble to
one of the piles, so that the total number of marbles on each side remains 9. You are allowed to move the marbles but not take any out.

We know that
X²+y²=9 -------> X²+y²=3²
is the equation of a circle with center (0,0) and radius r=3 units
so
<span>the translation of four units to the right and three units down is equals to move the center (0,0)--------> (0+4,0-3)------> (4.-3)
the new center of the circle is (4,-3)
the new equation is
(x-4)</span>²+(y+3)²=3²
see the attached figure
