Question 106370
Since it is equilateral, it must have equal sides. Furthermore, the dies are 5X-3, 6X-1, and 3X+2Y. Thus,

{{{5x-3=6x-1}}}
{{{5x-3+3=6x-1+3}}}
{{{5x+0=6x+2}}}
{{{5x=6x+2}}}
{{{6x+2=5x}}}
{{{6x-5x+2=5x-5x}}}
{{{x+2=0}}}
{{{x=0-2}}}
{{{x=-2}}}


But, {{{3x+3y}}} is also a side. Thus,

{{{3x+2y=6x-1}}}
{{{3(-2)+2y=6(-2)-1}}}
{{{-6+2y=-12-1}}}
{{{-6+6+2y=-12-1+6}}}
{{{0+2y=(-12-1)+6}}}
{{{2y=-13+6}}}
{{{2y=-7}}}
{{{y=-7/2}}}


Therfore, {{{x=-2}}} and {{{y=-7/2}}}
