1\/2[x一1\/2(x一1)十1]=2\/3(x一1)怎么解方程
如果\/是除号的话可以这样解。化简得3x 9=8x-8 解得x=17\/5
试用简便方法解方程1\/2(X-1\/2(X-1)+1)=2\/3(X-1)
1\/2(x-1\/2(x-1)-1+2)=2\/3(x-1) {将“+1”变为“-1+2”} 1\/2((x-1)-1\/2(x-1)+2)=2\/3(x-1) → 1\/2(1\/2(x-1)+2)=2\/3(x-1)1\/4(x-1)+1=2\/3(x-1) {去括号} 5\/12(x-1)=1 {移项，合并同类项} x-1=12\/5 x=17\/5=3.4 ...
试用简便方法解方程2\/1[x-2\/1(x-1)+1]=2\\3(x-1)
1\/2(x-1\/2(x-1)-1+2)=2\/3(x-1) {将“+1”变为“-1+2”} 1\/2((x-1)-1\/2(x-1)+2)=2\/3(x-1) → 1\/2(1\/2(x-1)+2)=2\/3(x-1)1\/4(x-1)+1=2\/3(x-1) {去括号} 5\/12(x-1)=1 {移项,合并同类项} x-1=12\/5 x=17\/5=3.4 ...
X-1\/2[X-1\/2(x-1)]=2\/3(x-1)
分析：含有多重括号的方程，先去小括号，再去中括号，再到大括号，一步一步解，解：X-1\/2[X-X\/2+1\/2]=2X\/3-2\/3 X-X\/2+X\/4-1\/4=2X\/3-2\/3 4X\/4-2X\/4+X\/4-1\/4=2X\/3-2\/3 3X\/4-1\/4=2X\/3-2\/3 3X\/4-2X\/3=1\/4-2\/3 9X-8X=3-8 X=-5 ...
解方程2x-1\/2[x-1\/2(x-1)]=2\/3(x-1)
解：2x-1\/2[x-1\/2(x-1)]=2\/3(x-1)2x-1\/2[x-1\/2x+1\/2)]=2\/3(x-1)2x-1\/2(1\/2x+1\/2)=2\/3(x-1)2x-1\/4x-1\/4=2\/3(x-1)两边同时乘以12，得 24x-3x-3=8(x-1)21x-3=8x-8 21x-8x=-8+3 13x=-5 x=-5\/13 ...
解方程 x-2[x-1\/2(x-1)]=2\/3(x+1)
解：X-2[X-1\/2X+1\/2]=2\/3X+2\/3 X-2X+X-1=2\/3X+2\/3 2X-2X-1=2\/3X+2\/3 -1=2\/3X+2\/3 -2\/3X=5\/3 X= - 5\/2 所以答案为X= - 5\/2 一元一次方程还是简单的，希望能帮到你！
