解:解方程,此方程的解为x = 14
6 - (3/8)x = 0.75
6 - (3/8)x = 75/100
6 - (3/8)x = 3/4
(3/8)x = 6 - 3/4
(3/8)x = 24/4 - 3/4
(3/8)x = 21/4
x = 21/4 ÷ 3/8
x = 21/4 × 8/3
∴x = 14
答:此方程的解为x = 14

6-3/8x=0.75
6-3/8x=3/4
3/8x=6-3/4=(6X4-3)/4
3/8xX8=(24-3)/4X8
3x=21X2
x=21X2/3
x=7X2
x=14

设x不等于0,得
48x-3=6x
42x=3
x=1/14≈0.0714285(714285循环)
