2x+7=3x-4解方程

解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7) 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+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8) 解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3 7x(x-6)+3x=4x(2x+5)怎么解这个方程 (x-3)(x+8)=(x+4)(x-7)+2(x+5)解方程, 方程(x-1/x-2)-(x-3/x-4)=(x-2/x-3)-(x-4/x-5)解为x=7/2,(1/x-7)-(1/ 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 x(2x-4)+3x(x-1)=5x(x-3)+8 解方程4x/(x^2+2x+4)-3x/(x^2-3x+4)=-7/3
