4X-5=5(X-5)
4x - 5 = 5x - 25
x = 20
4x-5=5x-25
-x=(-25+5)
-x=-20
x=20
不错呀 现在才开始放假就知道写作业 不错

x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
x-2x+3x-4x+5x.+99x-100x=25求解
2x+3x+4x+5x+x+6x+7x=100
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
提取公因式:已知x*x-5x+1=0 求x*x*x-4x*x-4x-1
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
x^-6x+5=x+4
5*4x+x*x=80
y=|-x.x+4x+5|
写过程x(x-1)+2x(x+1)-3x(2x-5)-x(3x-2)+2x(2-x)=-5x(x-2)-4
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
x-x/4=x/4+4x/5-30.
x-3/4x=(108-x)-4/5x
4x-7x=9-5x x=?
4x-3x(20-x)=5x
