6.2(x-2)-7(7-x)=12-3.2(9-x) 解方程,
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7)
解方程(x²-x+4)x-(x-1)(x²+2)=x+7
解方程(3x^2+9x+7)/(x+1)-(2x^2+4x-3)/(x-1)-(x^3+x+1)/(x^2-1)=0
解分式方程(5-2x)/(x^2-x-12)=5x/(x^2+x-6)+(10-7x)/(x^2-6x+8)得
解方程: x-5/x-6+x-8/x-9=x-7/x-8+x-6/x-7 过程!
解方程:x(x的平方-2)+2x的平方(x+3)-3x(5x-7)=x(3x的平方-9x+17)+2
⒈ 解方程 (X+7)/(X+6)+(X+9)/(X+8)=(X+10)/(X+9)+(X+6)/(X+5)
