8x+2(x-5)=508x+2(x-5)=508x+2(x-5)=508x+2x-10=5010x=60x=6将方程改写成:8X+2X-10=50即10X=60,所以X=6
8x+2(x-5)=50
8x+2(x-5)=50
8x+2(x-5)=50
8x+2x-10=50
10x=60
x=6
将方程改写成:8X+2X-10=50 即10X=60 ,所以X=6
解下列方程!就三道!解下列方程.1、x/x-2 - 1-x²/x²-5x = 2x/x-3(x/x-2 - 1-x²不是一起的!)2、5x/x²+x-6 - 5-2x/x²-x-12=7x-10/x²-6x+8(5x/x²+x-6 - 5-2x不是一起的!)3、x-4/x-5 + x-8/x-9=x-7/x-
x+5/x+1-3x-3/x+5=8x+28/x^2+4X-5-2(x+5)/(x+1)-(3x-3)/(x+5)=(8x+28)/(x^2+4X-5)-2
1.(1/X-1 )-2=X^-3X/X^-12.(X/X+1)^+5(X/X+1)+6=03.(8(X^+2X)/X^-1)+ 3(X^-1)/X^+2x
