- 解方程不会,请帮帮忙1.x
- 1.x-b/3=2-(x-a)/2
2.(7/x^2)+(1/x^2-x)=6/x^2-1
3.(x-2/x+2)+(x+2/2-x)=16/x^2-4
4.(x+7/x+6)+(x+9/x+8)=(x+10/x+9)+(x+6/x+5)
5.(1/a)+(a/x)=(1/b)+(b/x)
- 1. x-b/3= 2-(x-a)/2
解： x-b/3 =2-x/2+a/2
x+x/2 =2+a/2 +b/3
3/2x =2+a/2 +b/3
3x =4+a+2/3b
x =4/3 +a/3 + 2b/9
2.解：7/x^2+ 1/x^2 -x =6/x^2-1
7+1-x^3 =5
-x^3 =-3
x^3 =3
x =1
