1/3X+20+(X-1/4(1/3X+20))=X-3/8X这道题怎么解?

问题描述:

1/3X+20+(X-1/4(1/3X+20))=X-3/8X这道题怎么解?
怎么解方程,要有明确的算式
x*1/3-20+x*1/4-10+110=x
x*1/3-20+x*1/4+10+70=x
解方程

1/3X+20+(X-1/4*1/3X+1/4*20)=X-3/8X1/3X+20+(X-1/12X+5)=X-3/8X1/3X+20+X-1/12X+5=X-3/8x1/3X-1/12X+X-X+3/8X=-20-51/4X+3/8X=-255/8X=-258X=5/(-25)X=-1/5/8X=-1/40
