问题描述: 2-x/x-3整体+1/3-x=3(2)5x-4/2x-4=2x+5/3x-6整体-0.5解方程 1个回答 分类:数学 2014-10-28 问题解答: 我来补答 (2-x)/(x-3)+1/(3-x)=3(2-x)/(x-3)-1/(x-3)=3(2-x-1)/(x-3)=31-x=3x-94x=10x=2.5(5x-4)/(2x-4)=(2x+5)/(3x-6)-0.53(5x-4)/(6x-12)=2(2x+5)/(6x-12)-33(5x-4)/(6x-12)-2(2x+5)/(6x-12)+3=0(15x-12-4x-10)+3(6x-12)=011x-22+18x-36=029x=58x=2经检验x=2是增根 展开全文阅读
