X-(X*0.17)=34
x=12432.48 + x/1.17*0.17-80-(x/1.17*0.17)*0.03 求X 等于多少

x=12432.48+x/1.17*0.17-80-(x/1.17*0.17)*0.03x-x/1.17*0.17+(x/1.17*0.17)*0.03=12432.48-80[1-1/1.17*0.

(56-x)÷(34-x)=3

(56-X)=3(34-X)56-X=102-3X2X=46X=23

x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x

是这样的:x^5+x^4=x^3(x^2+x)=(x^2+x)[(x^3-1)+1]=(x^2+x)(x^3-1)+x^2+x=[x(x+1)(x-1)](x^2+x+1)+x^2+x=(x^3-x)

8x+5x=1.3 4.5x-3.2x=3.9 5.5x-x=9.9 11x-7x-26=34 列方程

①x=0.1②x=3③x=9.9/4.5④x=15很高兴为您解答,【学习宝典】团队为您答题.请点击下面的【选为满意回答】按钮,

3x+4(9-x)=34

3x+4(9-x)=343x+36-4x=34-x=-2x=2

x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?

x(1+2+...+9)=x(9-8-7-...-1)x=0记得采纳啊

(X+X)+(X-X)+(X*X)+(X/X)=100

(X+X)+(X-X)+(X*X)+(X/X)=1002X+0+X*X+1=1002X+X*X=99X(X+2)=99X=9再问:请问X(X+2)=99解为什么就等于9了呢没看懂再答:换成算术法你就明

X+X+X+X+X+X+100X=1690 问:X等于多少

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

设x1=4-√3,x2=4+√3,是方程X^2-8X+13=0的两根所以X1^2-8X1+15=2X^4-6X^3-2X^2+18X+23=(X+1)^2*(X^2-8X+13)+10=10所以原式=

3.5x+5x=34

3.5x+5x=348.5X=34X=34/8.5X=4

INPUT "x=";x

当X=51a=51/10取整=5b=51/10取余=1X=10*1+5=15所以,运行结果为15

(x-22)+(x-24)+(x-27)+(x-20)=x

(x-22)+(x-24)+(x-27)+(x-20)=xx-22+x-24+x-27+x-20=x4x-93=x4x-x=933x=93x=31

(X-10000)/(X/0.17)=0.1,求X,

(X-10000)/(X/0.17)=0.1X-10000=0.1*X/0.17X-10000=X/1.7X-X/1.7=100000.7X/1.7=10000X=10000÷0.7/1.7X=170

x/x平方-x+2=2x/x+1

x/x(x-1)+2=2x/(x+1)1/(x-1)+2=2x/(x+1)x+1+2(x-1)(x+1)=2x(x-1)x+1+2x²-2-2x²-2x=0-x-1=0-x=1x=
