未知数的运算规则 91⼀3.5X＝1.3应该怎么运算才符合规则

利用等式移项性质可以解决
91/3.5x=1.3
3.5x=91/1.3
3.5x=70
x=70/3.5
x=20
解出来了.....

。。。。要看楼主这个x在哪里了 如果在分母上 则是第二种解法
如果在这个分数后面 就是第一种解法

There are tear
That is what I waited in vain in 1000 for you transmigration
when I look back constantly pull tie him down in the cut trip
all your pride
can only fly in the picture

desert that was Playing Flute under the setting sun's Who
years stripping any scarred red are helpless
desolate castle who rebounded with pipa
just waiting for me come and gone
meet this life

fireworks fireworks fly sky Whom you charming

but seeing Huahua also drunk drunk
quicksand quicksand sky fly
Who you haggard

edge to edge, but is scattered
edge of water
