你好,李芸珂同学 这里有些,你可以参考下 1. 2(x-2)-3(4x-1)=9(1-x) 2. 11x+64-2x=100-9x 3. 15-(8-5x)=7x+(4-3x) 4. 3(x-7)-2[9-4(2-x)]=22 5.2(x-2)+2=x+1 6.2(x-2)-3(4x-1)=9(1-x) 7.11x+64-2x=100-9x 8.15-(8-5x)=7x+(4-3x) 9.3(x-7)-2[9-4...

多余的留作纪念吧! 15-(8-5x)=7x+(4-3x) 3(x-7)-2[9-4(2-x)]=22 3/2[2/3(1/4x-1)-2]-x=2 2(x-2)-3(4x-1)=9(1-x) ...

我也在找这是我找到的(x-2)-3(4x-1)=9(1-x) 11x+64-2x=100-9x 15-(8-5x)=7x+(4-3x) 7(2x-1)-3(4x-1)=4(3x+2)-1; (5y+1)+ (1-...
