1.5x(x-3)=60
解下列方程 4(6x+3)=60 2x+1.5x=17.5 2x+23*4 8x-3x=105 (
(1)6+2(x-3)=X (2)8-2(x-7)=x-(x-4) (3)2x-(1.5x-1)=2(1.5x-1)
x+17=3(x+13),2x-11.2=0.6x,2.5x-2.17=21.9-5.8x,8(x-1.5)=x+0.6
f(x)=x²+3x|x-2|
3x-60=x
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
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
3/x-1=4/x 6/x+1=x+5/x(x+1)
(1)1000*1.5^5-1.5x^4-1.5x^3-1.5x^2-1.5x-x>=2000
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!)+.
