Answer 2

$1.5x + 3.2y - 0.8 + 4.3y + 2.9x - 5.1y \\ \frac{3}{2} x + \frac{16}{5} y - \frac{4}{5} + \frac{43}{10} y + \frac{29}{10} x \frac{51}{10} y \\ \frac{1}{10} \times (15x + 32y - 8 + 43y + 29x - 51y) \\ \frac{1}{10} \times (44x + 24y - 8) \\ \frac{1}{10} \times 4(11 + 6y - 2) \\ \frac{1}{5} \times 2(11 \times + 6y - 2) \\ 2 \times \frac{1}{5} \times (11x + 6y - 2) \\ \frac{2}{5} \times (11 \times + 6y - 2)$
