7x-10-3-2x=16解方程
7x-10-3-2x=16解方程
解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7)
解方程: 2x^10=x^4+x^7
解方程:7x-2x+3x=36
解方程7x-2x+3x=36
解方程:x^2/9+16/x^2=10/3(x/3-4/x)
解方程:4(x^2-7x+10)-(2x+3)(2x-1)=-21
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+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
