X-(2x-180)+X÷2=180要怎么解?

(x-2)+(x+2)+(x/2)+(2*x)=180 (180x-36*x)/(x+2x)*2x=(180x-36*x)/(x+2x)*x+36x 这个怎么解啊···· x+x÷3+2x-30=180 180=( )x( )x( )x( ) ×( ) （x-5）+（x+5）+2x+（x÷2）=180的解 化简 [3x/(x+2)-x/(x=2)]÷x/(x^2-4)化简 [3x/(x+2)-x/(x-2)]÷x/(x^2-4 f(x)=x^2+x (x X+2X+(180-3X)=180 怎么算? （x/5+180）+ 2*(x/5+180) = x 1.(X-2)*180+[180-(X-2)*180/X]=6002.(X-2)*180-(X-2)*180/X=3180 x+2x+2x=180° 急 (x-2)*180/x*x=360咋解 x+3x+1+x/2-1=180 x分之180-x+0.5x分之=2 设f(x)=x+2÷x(x 180/(x-15)-180/x=2 X^2-3X-2=0,求( x - 2x-1/x )÷(x-1)/(x^2-2x) (x²-x+1)÷(x²-x-1)=(x²+x)÷(x²+x-2)解方程
