You can put this solution on YOUR website!
Let +x+ = the number of elephants
that were ill
+x+%2B+300+ = the total number of elephants
The number that were ill was:
+%281%2F3%29%2A%28+x+%2B+300+%29+
+%281%2F3%29%2Ax+%2B+100+
Now I can say:
+x+=+%281%2F3%29%2Ax+%2B+100+
+%282%2F3%29%2Ax+=+100+
+2x+=+300+
+x+=+150+
150 elephants were ill
There were +x+%2B+300+=+150+%2B+300+
+150+%2B+300+=+450+
450 elephants total
