12x+8 = 2(5x+6)
12x+8 = 10x+12
12x-10x = 12-8
2x = 4
x = 2

then DE = 5x+6 = 5(2)+6 = 16

If s represents the number of songs Kim downloads, her expenses for a month must satisfy the inequality
  5.00 + 0.58·s ≤ 13.00

To solve this, subtract 5.00 to get the s-term by itself, then divide by the coefficient of s.
  0.58·s ≤ 8.00
  s ≤ 8.00/0.58 ≈ 13.79
The number of songs must be an integer, so we conclude Kim can download 13 songs, but not 14 songs.

Kim can download 13 songs without exceeding her budget.
