2(2x-3)/0.01-2.5=0.02-2x/0.02-7.5
2(2x-3)/0.01-2.5=0.02-2x/0.02-7.52(2x-3)/0.01-2.5=0.02-2x/0.02-7.5
4x-6/0.01-2.5=0.02-2x/0.02-7.5
1/100(4x-6)-2.5=1/50(0.02-2x)
1/25x-3/50-2.5=1/2500-1/25x
2/25x=2.5604
x=32.05
3道简单的分式方程,1.3/(1-x^) = 2/(1+2x+x) - 5/1-2x+x^2.5x/(x^+x-6) + (2x-5)/(x^-x-12) = (7x-10)/(x^-6x+8)3.(x+1)/(x+2) + (x+6)/(x+7) = (x+2)/(x+3) + (x+5)/(x+6)
(X+1)X(X+2)X(X+3)=504
一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
2(x+1)-(3-x)=2(1.5x-2.5)
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
x-2x+3x-4x+5x.+99x-100x=25求解
x+3x+x-2+x+x+50%x=188 求x
2x+3x+4x+5x+x+6x+7x=100
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
3(x-2)=x(x-2)
0.3x+7x-0.25x=21.15 x+7=2x+3 1.2x+1=0.01x+三分之五 4x-26=3x+4 6x+2=5x+110.3x+7x-0.25x=21.15x+7=2x+31.2x+1=0.01x+三分之五4x-26=3x+46x+2=5x+114(x+1)=x+10
X+X+X+(X-1)+(X-2)+(X-3)+(X-4)=10(X-3)+(X-4)
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
x(x-3)=2(3-x)
