Question 821009
Melissa has twice as many pencils as Elle. The difference in pencils is 15. How many pencils does each of the girls have?
------------------------------
Equations:
m = 2e
m-e = 15
----------
Substitute for "m" and solve for "e"::
2e-e = 15
e = 15 (Elle has 15 pencils)
----
Solve for "m":
m = 2e
m = 30 (Melissa has 30 pencils)
