Peter delivers 110 newspapers on the weekend. He delivers 20 more papers on Sunday than on Saturday. How many papers does he deliver each day?
-----------------------------
Let number delivered on Saturday be "x".
Then number delivered on Sunday is "x+20".
-----------------
Equation:
x + x+20 = 110
2x + 20 = 110
2x = 90
x = 45 (# he delivers on Saturday)
x+20 = 65 (# he delivers on Sunday)
