30/(30+60-X)=88/(88+100),X=?
30/(30+60-X)=88/(88+100)
30/(90-X)=88/(88+100)
30/(-X)=88/(-2*88+100)
30/X=88/76

解方程 40%x+2=12 x+25%x=10 x-30%x=1.4 15x-60=240 x+1解方程40%x+2=12x+25%x=10x-30%x=1.415x-60=240x+129%x=88
88=x(30-2x)
4x+2(30-x)=88
60x(x-4)=30x
x+(30-x)=60
x-60%x-25%x=25%x-30
(x+30)*(x-18)=x*x
2x+4(30-x)=88咋做
2x+4(30-x)=88咋做
4x+2(30-x)=88
4X/88=(X-60)/20 x=?
60(30x)=40x+20(30+x)+1200
x/45=(x+30)/60+1 x=270x/45=(x+30)/60+1x=270
X+60%X=30解方程
x/45=1+(x+30)/60
X/45=(X+30)/60-1
60*(X-4)=30X
