X+2Y=-10
-X+3Y=-9 ADDING THE TWO EQUATIONS WE GET
--------
5Y=-19 OR Y=-19/5 SUBSTITUTING -19/5 FOR Y IN EQUATION 1 WE GET

X+2(-19/5)=-10 OR X-38/5=-10 OR X=-10+38/5 OR X=(-50+38)/5 OR X=-12/5

PROOF -(-12/5)+3(-19/5)=-9 OR 12/5-57/5=-9 OR (12-57)/5=-9 OR -45/5=-9 OR 
-9=-9 &amp; -12/5+2(-19/5)=-10 or -12/5-38/5=-10 or (-12-38)/5=-10 or -50/5=-10 or
-10=-10</PRE>
