You can put this solution on YOUR website!
Let +x+ = amount invested at 9%
+2800+-+x+ = amount invested at 5%
-----------
given:
+.09x+%2B+.05%2A%28+2800+-+x+%29+=+180+
+.09x+%2B+140+-+.05x+=+180+
+.04x+=+40+
+x+=+1000+
+2800+-+x+=+1800+
Amount invested at 9% is $1,000
Amount invested at 5% is $1,800
check:
+.09%2A1000+%2B+.05%2A1800+=+180+
+90+%2B+90+=+180+
+180+=+180+
OK
