再问： 还有 方程 代数式化简求值 应用题 谢谢
再答： 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(2-x)]=22 10.3/2[2/3(1/4x-1)-2]-x=2 11.5x+1-2x=3x-2 12.3y-4=2y+1 13.87X*13=5 14.7Z/93=41 15.15X+863-65X=54 16.58Y*55=27489 17.2（x+2）+4=9 18.2(x+4)=10 19.3(x-5)=18 20.4x+8=2(x-1) 21.3(x+3)=9+x 22.6(x/2+1)=12 23.9(x+6)=63 24.2+x=2(x-1/2) 25.8x+3(1-x)=-2 26.7+x-2(x-1)=1 27.x/3 -5 = (5-x)/2 28.2(x+1) /3=5(x+1) /6 -1 0.4(x-0.2)+1.5=0.7x-0.38 x=6 30x-10(10-x)=100 x=5 4(x+2)=5(x-2) x=18 120-4(x+5)=25 x=18.75 15x+863-65x=54 x=16.18 3(x-2)+1=x-(2x-1) x=3/2 11x+64-2x=100-9x x=2 应用题网址：http://zhidao.baidu.com/question/226395927.html
