(3x - 2)/4 + (-2x + 1)/35. -2(3x - 2y) + 3(5x + y)6. (x + y)/2 - (3x - 25y)/67. (2/9)xy^2 ÷ (4/15)xy8. (-3x)^2 ÷ 2x × 4y9. (-3a)^2 × 2b ÷ (6/7)ab2. 解き方の手順1. 10 ÷ (-2) + 8 = -5 + 8 = 32. (-6)^2 ÷ 12 × 4 = 36 ÷ 12 × 4 = 3 × 4 = 123. 8 + (-6^2 + 30) ÷ 12 = 8 + (-36 + 30) ÷ 12 = 8 + (-6) ÷ 12 = 8 - 1/2 = 15/24. (3x - 2)/4 + (-2x + 1)/3 = (9x - 6)/12 + (-8x + 4)/12 = (9x - 6 - 8x + 4)/12 = (x - 2)/125. -2(3x - 2y) + 3(5x + y) = -6x + 4y + 15x + 3y = 9x + 7y6. (x + y)/2 - (3x - 25y)/6 = (3x + 3y)/6 - (3x - 25y)/6 = (3x + 3y - 3x + 25y)/6 = 28y/6 = 14y/37. (2/9)xy^2 ÷ (4/15)xy = (2/9)xy^2 × (15/4)(1/xy) = (30/36)y = (5/6)y8. (-3x)^2 ÷ 2x × 4y = 9x^2 ÷ 2x × 4y = (9/2)x × 4y = 18xy9. (-3a)^2 × 2b ÷ (6/7)ab = 9a^2 × 2b × (7/6)(1/ab) = (126/6)a = 21a3. 最終的な答え1. 32. 123. 15/24. (x - 2)/125. 9x + 7y6. 14y/37. (5/6)y8. 18xy9. 21a
