(x-360)*(2/7)+360=1/2x
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
6X-(360X-0.5X)=2×(360X-0.5X)
2x²+7x+1=0 x(x-1)=3x+7
X.(X十1)x(X十2)x(x十3) =360
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
1/x-2=7x/(x-2) -3
(x)-2x·x-x-2x+1=0求x的值,
解方程:(2x-3)(x+1)-x(x-7)=(x-3)(x+2)
方程 3x(7-2x)+5x(2x-1)=4x(x-3)+56
(1)6+2(x-3)=X (2)8-2(x-7)=x-(x-4) (3)2x-(1.5x-1)=2(1.5x-1)
计算:1/(x^2-7x+10)+1/(x^2-x-2)+1/(x^2+5x+4)+1/(x^2+11x+28)=( )
