3(x-2)=7-2x(解方程)
解方程 6x(7-x)=36-2x(3x-15)
解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7)
解方程:7x-2x+3x=36
解方程7x-2x+3x=36
解方程,( 2x-1)²=x(3x+2)-7
解方程X^3-7X^2+14X-8=0
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)
