Question 817804
On a mother's 25-mile commute to work, she drops her daughter off at a child care center. The first part of the trip is 7 miles less than the second part. How long is each part of her morning commute?
x + x+7 = 25
2x = 18
x = 9
---------------- 
first part:: 9 mi 

second part:: x+7 = 16 mi 
=======================
Comment: You can check the algebra but you have to 
correctly interpret the wording of the problem; no
check for that except to read it again.
