1.3X+1.5X=0.14 7X-3X+0.04=0.4解方程
1.3X+1.5X=0.14 7X-3X+0.04=0.4解方程
2.8x=0.14
x=0.2
4x=0.36
x=0.09
2.8x=0.14 x=0.05
4x=0.36 x=0.09
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!)+.

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)
2x+3x+4x+5x+x+6x+7x=100
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
3x+7x=( )+( )X( )
7x-3x+x=60
(x+7)+x+3x=17
(x+1)/(x+2)+(x+8)/(x+9)解答x+1/x+2+x+8/x+9=x+2/x+3+x+7/x+8
x+ x+(x*50%)=1.5X?
（X+X)+(X-X)+(X*X)+(X/X)=100
1.3x+1.5x=0.14
x-3(20-x)=3x-7(9-x)
