Решение:

• \( (39 - 24) : 5 = 15 : 5 = 3 \)
• \( (49 - 31) : 6 = 18 : 6 = 3 \)
• \( (48 - 32) : 8 = 16 : 8 = 2 \)
• \( 75 - (3 \times 4) = 75 - 12 = 63 \)
• \( 96 - (2 \times 7) = 96 - 14 = 82 \)
• \( 85 - (3 \times 5) = 85 - 15 = 70 \)
• \( 2 \times 9 + 80 = 18 + 80 = 98 \)
• \( 3 \times 6 + 50 = 18 + 50 = 68 \)
• \( 4 \times 5 + 46 = 20 + 46 = 66 \)
