解方程。
$5.2x - 0.8 = 9.6$ $7.5 - 2.4x = 2.7$ $13x - 7x = 1.8$
$2.2x - 5×2 = 23$ $5x - 80 = 180$ $0.5×10 + 5x = 50$
$180 + 6x = 330$ $27x + 31x = 145$ $3x + 95×3 = 540$
$1.2x + 2.5 = 18.1$ $6x + 18x = 96$ $3x + 216 = 414$
$2.1x + 6.3 = 13.23$ $4.3x - 8.99 = 12.51$ $4.2 + 6x = 22.8$

答案： $P_{(x)} \quad x = 2 \quad x = 15 \quad x = 25 \quad x = 13 \quad x = 3.3 \quad x = 2 \quad x = 52$
$x = 2.5 \quad x = 4 \quad x = 5 \quad x = 0.3 \quad x = 9 \quad x = 85 \quad x = 66 \quad x = 3.1$
