Jawaban:1. 1(4a - 2b) - (a + 5b)= 4a - 2b - a - 5b= 3a - 7b2. 2(x^2 + 3x + 7) - (-6x^2 - 2x + 5)= 2x^2 + 6x + 14 + 6x^2 + 2x - 5= 8x^2 + 8x + 93. (8x + 7y) / (x - 2y) - (x + 4y - 1) / (2x + 6)(Soal ini tidak bisa disederhanakan lebih lanjut tanpa nilai x dan y)4. 3(x + 5y)= 3x + 15y5. 6(5x - 2y + 1)= 30x - 12y + 66. -4(-2a + b)= 8a - 4b7. (3a + 4b - 5) × (-2)= -6a - 8b + 108. (7a - 4b) × 5= 35a - 20b9. 1/4 (-8x - 2y)= -2x - 1/2 y
