To answer this item, first we let any variable be the number of cds she can buy. We let x be that number in our case. The total amount of money she will be needing in order to buy x cds is 14x. Add this amount to 23, the sum should be 65. The equation can be simplified into,
14x + 23 = 65
Solving for x,
x = (65 - 23) / 14
