Answer:

The wallet contains 5 $5 notes and 15 $1 coins

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 40

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 405x + 3x = 40

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 405x + 3x = 408x = 40

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 405x + 3x = 408x = 408x/8 = 40/8

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 405x + 3x = 408x = 408x/8 = 40/8x = 5

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 405x + 3x = 408x = 408x/8 = 40/8x = 55 * 5 + (1 + 3 * 5) = 40

The wallet contains 5 $5 notes and 15 $1 coins5x + (1*3x) = 405x + 3x = 408x = 408x/8 = 40/8x = 55 * 5 + (1 + 3 * 5) = 4025 + 15 = 40
