解方程：7-x+5/2=2-x/5-3x “/”为除号 另还有两个在图中x+5

解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7) 解方程：x(3x-4)+2x(x+7)=5x(x-7)+90 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 解分式方程：(x+1)/(x+2)+(x+6)/(x+7)=(x+2)/(x+3)+(x+5)/(x+6) 解分式方程: (x-1)/(x-2)+(x-6)/(x-7)=(x-2)/(x-3)+(x-5)/(x-6) 解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7) 解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3 解方程 (x+2)/(x+1) - (x+4)/(x+3)=(x+6)/(x+5)-(x+8)/(x+7) 解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6) 解方程：(3-x)/(1-x)+(x^2-2)/(x^2-8x+7)=1+(x-5)/(x-7) 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, 5x(x+7)(x+4)=5x(x^2+11X)解方程, 解方程(x-3/x)-(3-x/x+1)=5x-15/2x+2 解方程：(x-2)(x^2-6x-9)=x(x-5)(x-3)
