5x-0.5=8 [x-4.6]×2.3=9.338 3x-1.45=2x+1.45 3.5x+x-14=18.4
以上的,怎么解方程,步步要列出来

5x-0.5=8
5x=8.5
x=8.5÷5
x=1.7
[x-4.6]×2.3=9.338
x-4.6=9.338÷2.3
x-4.6=4.06
x=4.06+4.6
x=8.66
3x-1.45=2x+1.45
3x-2x=1.45+1.45
x=2.9
3.5x+x-14=18.4
3.5x+x=18.4+14
4.5x=32.4
x=32.4÷4.5
x=7.2

5x-0.5=8 [x-4.6]×2.3=9.338 3x-1.45=2x+1.45 3.5x+x-14=18.4 x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少? x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x 已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值 1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550 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)+(X-X)+(X*X)+(X/X)=100 y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1 已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^5+x^6+x^7+x^8的值设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10), (3-x)/(1-x)-(5-x)/(7-x)+(x^2-x)/(x^2-8x+7)=1 解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
