(14-x)×5=50-x(14-x)×5=50-x(14-x)×5=50-x5
(14-x)×5=50-x
(14-x)×5=50-x
(14-x)×5=50-x
5
(14-x)×5=50-x
5*(x-2)=4*(x+3) 2x+(50-x)*4=140 3x-(8-x)=20*4 200x=(x-0.5)*240 12x+34=14*(x-4)
若(x+a)x(x+2)=x的平方-5x-14
14x-4(x+5)=30.5 x=?
一元二次方程解答!x(5x+4)=5x+44x^2-45=31x-3x^2+22x-24=0(x+8)(x+1)= -12(3x+2)(x+3)=x+14
1、1/2x=2/x+32、x/x+1=(2x/3x+3)+13、2/x-1=4/x²-14、5/x²+x-1/x²-x=0
5x-(x-2)=14
(x-5)(x+3)+x(x+6)=-17 (x+x)(x+x+1)-6=0用因式分解
5x+7X[14-X]=28?X是什么?
5x+x=14
5x+15x =( + )x =20x
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
matlab解数值分析题p=(x-1)*(x-2)*(x-3)*(x-4)*(x-5)*(x-6)*(x-7)*(x-8)*(x-9)*(x-10)*(x-11)*(x-12)*(x-13)*(x-14)*(x-15)*(x-16)*(x-17)*(x-18)*(x-19)*(x-20)解为1,2,3……,20取多个非常小的数用软件工具求解方程p(x)+n*x^19=0,并
3/x-1=4/x 6/x+1=x+5/x(x+1)
2x-10=15x+30,6x-6=6x+2,9-3x=2x-8,5x=9x-50 ,5y-5=12-6y,15x-9=7x31最好的给补充财富和评满意答案.2题是9x-3(x-2)=6x+2
(x+x)+(x-x)+(x/x)=11.2
f(x)=(x+2)/(5x-1) 的反函数f-¹(x)=?
5(x²-x)=3(x²+x)
