+Let+Seth%27s+height+=+x+
+x+%2B+15+ = Jack's height
---------------------------------
+3%2F4+=+x%2F%28+x%2B15+%29+
+3%2A%28+x%2B15+%29+=+4x+
+3x+%2B+45+=+4x+
+x+=+45+
+x+%2B+15+=+60+
Seth is 45 inches tall
---------------------------
check:
+3%2F4+=+45%2F60+
+3%2F4+=+%28+15%2F15+%29%2A%28+3%2F4+%29+
OK
