x/16 + 15/60 = x/9.6 - 15/60
x/16 + 15/60 = 0.6x/16 - 15/60
x/16 = 0.6x/16 - 30/60
0.4x/16 = - 30/60
x = - 20追问答案是12追答上面计算有误，重算一下。
x/16 + 15/60 = x/9.6 - 15/60
x/16 = 10x/96 - 1/2
4x/96 = 1/2
x/24 = 1/2
x = 12
x/16 + 15/60 = 0.6x/16 - 15/60
x/16 = 0.6x/16 - 30/60
0.4x/16 = - 30/60
x = - 20追问答案是12追答上面计算有误，重算一下。
x/16 + 15/60 = x/9.6 - 15/60
x/16 = 10x/96 - 1/2

x/16+15/60=x/9.6-15/60,
x/9.6-x/16=15/60+15/60,
10x/96-6x/96=1/2,
4x/96=1/2,
x=12
x/9.6-x/16=15/60+15/60,

x/16+15/60=x/9.6-15/60
x/16-x/9.6=-15/60-15/60
-0.4x/9.6=-1/2
x/24=1/2
x=12追问-0.4x/9.6是怎么得的追答x/16-x/9.6
=x*(1/16-1/9.6)
=x*(0.6/9.6-1/9.6)
=x*(-0.4/9.6)
=-0.4x/9.6
x/16-x/9.6=-15/60-15/60
-0.4x/9.6=-1/2
x/24=1/2
x=12追问-0.4x/9.6是怎么得的追答x/16-x/9.6
=x*(1/16-1/9.6)
=x*(0.6/9.6-1/9.6)
=x*(-0.4/9.6)
=-0.4x/9.6
