5x+(20-x)=52
5x+(20-x)=52
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
(x-20%x)+5=x-3
5*(x-2)=4*(x+3) 2x+(50-x)*4=140 3x-(8-x)=20*4 200x=(x-0.5)*2
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
4x-3x(20-x)=5x-7x(20-x)
4x-3x(20-x)=5x-7x(20-x)的解法
3/x-1=4/x 6/x+1=x+5/x(x+1)
求未知数x x-20%x=52 (1-60%)X=24
解方程:3X+8=5X-6X (3X+2)-X=218 80+X=3(52-X)
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!)+.
