5x减8分之5等于12分5怎么算（要过程）？

Answer 1

因为都有一个五可以把我约掉，这样子就是1/12，加上1/8，这个等于，等于5/24，所以结果就出来了x=5/24

Answer 2

5x-5/8=5/12
5x=5/12+5/8
5x=10/24+15/24
5x=27/24
x=27/24÷5
x=27/24*1/5
x=27/120 (120分之27)

Answer 3

5x-5/8=5/12移项
5x=5/12-5/8通分
5x=10/24-15/24
5x=-5/24
x=-1/24

Answer 4

5X-5/8=5/12
5X=5/12+5/8
X=（5/12+5/8）/5
=1/12+1/8
=（2+3）/24
=5/24

Answer 5

5x-5/8=5/12
5x=5/12+5/8
x=(5/12+5/8)x1/5
x=5/12x1/5+5/8x1/5
x=1/12+1/8
x=2/24+3/24
x=5/24
