解方程7x+3=3x+19

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x(x-7)=3x+24 解方程7x+3=3x+19 解方程:(x^2 + 7x + 5)^2 - 3x^2 - 21x=19 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) 解分式方程 x-7/x-9+x-3/x-5=x-4/x-6+x-6/x-8 解方程(x+1/x+2)-(x+2/x+3)=(x+5/x+6)-(x+6/x+7)
