解方程[2(x+3)]/5=(3/2)x-[2(x-7)]/3 要简练,要准确!

解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7) 解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6) 解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7) 解方程(x+1/x+2)-(x+2/x+3)=(x+5/x+6)-(x+6/x+7) 解方程：x+2/x+1-x+3/x+2=x+6/x+5-x+7/x+6 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 解方程：2（x-2)(x+3)-(2x-5)(x-1)=3x+7 解方程 2(x-2)(x+3)-(2x-5)(x-1)=3x+7 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/
