解方程 x+3.2=6.4 x-1.8=4 x-2=15 1.6x=6.4 x/7=0.3 x/3=2.1
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
方程(x-1/x-2)-(x-3/x-4)=(x-2/x-3)-(x-4/x-5)解为x=7/2,(1/x-7)-(1/
