解:解方程, 此方程的解为x = -35
1 一 1/5X 一 (1/5X + 4.5) = 10.5
1 - (1/5)x - (1/5)x - 4.5 = 10.5
1 - (2/5)x = 10.5 + 4.5
1 - (2/5)x = 15
(2/5)x = 1 - 15
(2/5)x = -14
x = -14 ÷ 2/5
x = -14 × 5/2
∴x = -35
答:此方程的解为x = -35
1 一 1/5X 一 (1/5X + 4.5) = 10.5
1 - (1/5)x - (1/5)x - 4.5 = 10.5
1 - (2/5)x = 10.5 + 4.5
1 - (2/5)x = 15
(2/5)x = 1 - 15
(2/5)x = -14
x = -14 ÷ 2/5
