Total weekday hrs worked is:
+2%2A5+=+10+ hrs
Let +x+ = his hourly wage for weekdays
+x+%2B+2+ = his hourly wage for saturdays
---------------------------------------
+10x+%2B+8%2A%28+x+%2B+2+%29+=+142+
+10x+%2B+8x+%2B+16+=+142+
+18x+=+126+
+x+=+7+
He works 7 hrs on weekdays
---------------------------
check:
+10x+%2B+8%2A%28+x+%2B+2+%29+=+142+
+10%2A7+%2B+8%2A%28+7+%2B+2+%29+=+142+
+70+%2B+8%2A9+=+142+
+70+%2B+72+=+142+
+142+=+142+
OK
