<PRE><B>Question 67570</B>
4X-3Y=8
2X+5Y=-9 NOW MULTIPLY THE SECOND FORMULA BY -2 AND ADD.
-4X-10Y=18
4X-3Y=8
----------------------------
-13Y=26
Y=26/-13
Y=-2 SOLUTION NOW SUBSTITUTE (-2) FOR Y AND SOLVE FOR X
4X-3(-2)=8
4X+6=8
4X=8-6
4X=2
X=2/4
X=1/5 OR .5 SOLUTION
THUS THE SOLUTIONS ARE D)1/2,-2 
PROOF
2(.5)+5(-2)=-9
1-10=-9
-9=-9
