解:解方程,此方程的解为x = 312/11
2x - (1/3)x + 2x = 104
2x + 2x - (1/3)x = 104
4x - (1/3)x = 104
(12/3)x - (1/3)x = 104
(11/3)x = 104
x = 104 ÷ 11/3
x = 104 × 3/11
x = (104×3)/11
∴x = 312/11
答:此方程的解为x = 312/11
2x - (1/3)x + 2x = 104
2x + 2x - (1/3)x = 104
4x - (1/3)x = 104
(12/3)x - (1/3)x = 104
(11/3)x = 104
x = 104 ÷ 11/3
x = 104 × 3/11
x = (104×3)/11
∴x = 312/11
答:此方程的解为x = 312/11
