2x^4-4x^3-7x^2+9=0
x/(x+27) = 0.38
2.7 = 10^(11.76-2x)+10^(2.76-x)+10^(-5.14)+10^(x-16.64)+10^(2x-29.44)+2*10^(14.52-3x)
xy/(x+y)=a/2 a=0.868 x=92.3
2.7 = 10^(11.76-2x)+10^(2.76-x)+10^(-5.14)+10^(x-16.64)+10^(2x-37.44)+2*10^(14.52-3x)
2.7 = 10^(11.76-2x)+10^(2.76-x)+10^(-5.14-x)+10^(x-16.64)+10^(2x-37.44)+2*10^(14.52-3x)
(x-60):(x+60)=2:3
3*x^4-2*3.336*x^2-1=0
35/85=21/x
(100-x)×0.84=(60-x)÷0.61

(10/13-x/500)*(10/13-x/500)=x/500
(10/13-x)*(10/13-x)=x
k-(5/13-k)*(5/13-k)=0
500*x-(5/13-x*500)*(5/13-x*500)=0
500*x-(5/13-x*500)*(5/13-x*500)
500*x-(5/13-x*500)*2
0.8t^2+5t-4=0
500*x-(5/13-x/2)*2
