5X+(120-X)/5=312怎么解?

5X+(120-X)/5=312怎么解?
5X+(120-X)/5=312
两边都乘以5
25x+120-x=1560
25x-x=1560-120
24x=1440
x=1440÷24
x=60

5X+(120-X)/5=312
5X+24-X/5=312
5X-X/5=312-24
24X/5=288
X=288*5/24
X=60

不懂可追问,有帮助请采纳,谢谢!

5X+(120-X)/5=312
25X+(120-X)=1560
24X+120=1560
24X=1560-120=1440
X=60

5X+24-0.2X=312
4.8X=312-24
X=60
