方程(7/12X+24)/(5/12x-24)=5/3完整的该怎么解？

Answer 1

(7/12X+24)/(5/12x-24)=5/3
解：3(7/12X+24)=5(5/12x-24)
21/12x+72=25/12x-120
25/12x-21/12x=120+72
4/12x=192
1/3x=192
x=576
二楼，三楼，四楼回答的一塌糊涂。

Answer 2

(7/12X+24)*3=(5/12x-24)*5
24*5+24*3=5*5/12x-7*3/12X
24*8=4/12X
X=576

Answer 3

(7/12X+24)/(5/12x-24)=5/3
3(7/12X+24)=5(5/12x-24)
21/12X+72=25/12X-120
72+120=(25-21)/12X
192=4/12X
X=4/192/12=1/576

Answer 4

(12/7x+24)/(12/5-24)=3/5 12/7x+24)/5=(12/5-24)/3 7/60x+48=36/5x-56 5/36x-7/60x=56
25/180x-21/108x=56 x=56*45 x=2520

Answer 5

X=24X24
或：
X=1/24x24

Answer 6

(7/12X+24)/(5/12x-24)=5/3交叉相乘得3（7/12+24）=5(5/12x-24)整理可得X=576
