再答：求采纳谢了

解由题意得43.2-36.5/X=0.543.2-0.5=36.5/X42.7=36.5/XX=0.85

0.77x=0.82×7-4.20.77x=1.54x=1.54÷0.77x=2

1.3x-3.2=13.71.3x=13.7+3.21.3x=16.9x=16.9/1.3x=13

9.2X-X=49.2(9.2-1)X=49.28.2X=49.2X=49.2÷8.2X=6

7.6x-4x=3.63.6x=3.6x=1

20×0.4-1.2x=5.68-1.2x=5.61.2x=2.4x=2

9.5X-5X=0.94.5X=0.9X=0.9÷4.5X=0.2

1.8-2x=0.61.8-0.6=2x1.2=2xx=1.2÷2x=0.6

0.7x-0.6x=0.010.1x=0.01x=0.1

(x+1)34%+0.1x=(x-1)60%0.34(x+1)+0.1x=0.6(x-1)0.34x+0.34+0.1x=0.6x-0.60.34x+0.1x-0.6x=-0.6-0.34-0.16x

X减0点76X等于0点96X-0.76X=0.960.24X=0.96X=0.96÷0.24X=4

x+2.5x=0.7（1+2.5)x=0.73.5x=0.7x＝0.2

17.28-4x=5.6x9.6x=17.28x=17.28/9.6x=1728/960x=1.8

x-24.7=39.6方程两边同时加上24.7x-24.7+24.7=39.6+24.7x=64.3再问：x+4.5=23.52用解方程再答：两边同时减去4.5x+4.5-4.5=23.42-4.5x

2.8x-0.6=52.8x=5.6x=5.6/2.8x=2

x(18-x)=65x^2-18x-65=0(x-13)(x-5)=0x=5或13

再答：抱歉题目看错了！再答：

x(x^2-1)=0解出x=-1、0、1
