Let X be the cost of the CD's. The movie costs 7 dollars more than the CD's. So the movie is X+7. Together, the movie plus the CD's equals 38. This can be written as: x+x+7=38 Subtract 7 from both sides, and combine the x's and you have: 2x=31. Divide both sides by 2 and we find that X, the cost of the CD's, is: x=15.5 Which means that the cost of the movie is 22.5. Or, written as currency, the CD's are $15.50 and the movie was $22.50.
