Question 513858
Sandi bought 6 yards of material. She wants to cut it into two pieces so that the difference between the lengths of the two pieces will be 1.5 yards. What should be the length of each piece? 
-----
Equations:
x + y = 6 yds
x -y = 1.5
----
Add and solve for "x":
2x = 7.5
x = 3.75 (one of the pieces)
-----
Solve for "y":
x + y = 6
3.75 +y = 6
y = 2.25 yds
