Let +I%5Bm%5D+ = the income of the man
Let +I%5Bw%5D+ = the income of the wife
---------------------------------
For man:
+I%5Bm%5D+%2F+4000+=+5%2F3+
+3I%5Bm%5D+=+5%2A4000+
+I%5Bm%5D+=+20000%2F3+
+I%5Bm%5D+=+6%2C666.+67+
----------------------
For wife:
+I%5Bw%5D+%2F+4000+=+3%2F1+
+I%5Bw%5D+=3%2A4000+
+I%5Bw%5D+=+12000+
