Question

x÷(x-44)×100%=94%解方程？

Answer 1

x÷(x-44)×100%=94% 将百分数先转化为分数有
x÷(x-44)x1 = 0.94
x÷(x-44) = 0.94
x=0.94*(x-44)
x=0.94x-41.36
x-0.94x=-41.36
0.06x=-41.36
x=-41.36÷0.06
x≈-689.33

Answer 2

解：x/(x－44) × 100%=94%
x/(x－44)=0.94
两边同乘(x－44)：x=0.94(x－44)
x=0.94x － 41.36
x － 0.94x=-41.36
0.06x=-41.36
x=-41.36÷0.06
x=-2068/3
经检验x=-2068/3不使x－44=0，所以是方程的解
