(3X-2)×7=2X(35-21)解方程
解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7)
解方程⑴ x/(2x^2-11x-21)=(x+7)/(x^2-12x+35)
解方程:7x-2x+3x=36
解方程7x-2x+3x=36
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-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
解方程:4(x^2-7x+10)-(2x+3)(2x-1)=-21
