(300-1)÷x=5分之1299÷x=5分之1x=299÷5分之1x=299×5x=1495
原式=[3x/(x-1)-x/(x-1)]/[x/(x^2-1)]=[2x/(x-1)]/[x/(x+1)(x-1)]=2x+2解不等式组:x-6(x-2)≥2.(1)4x-2
楼主说的除指的是除以吧?3/4x=1/2x=(3/4)/(1/2)=3/2
∵除式是x2-x+1,商式是x+1,余式是3x,∴被除式是:(x2-x+1)(x+1)+3x=x3+3x+1.故选:A.
等会回家告诉你再答: 再答:请采纳谢谢~
(x+8)÷1.2=20x+8=20x1.2x+8=24x=24-8x=16
x=9/25×15x=27/5
X-1除X-3>0而其等价于不等式(x-1)(x-3)>0所以解集为x3
10除X=10分之1X除以10=10分之1x=1
∵1/(x^2+3x+2)+1/(x^2+5x+6)+1/(x^2+7x+12)=1/(3x),∴1/[(x+1)(x+2)]+1/[(x+2)(x+3)]+1/[(x+3)(x+4)]=1/(3x)
(5x-1)/6=7/33*(5x-1)=6*715x-3=4215x=45x=3
x÷x²+3x+2=2x+2-x÷x²+2x+1=x+1-1÷3x+6=?
10x/3+1/5=1(50x+3)/15=150x+3=1550x=12x=6/25
x/(1-24%)=150x=150*76%x=114
7.2/4*x=4.321.8x=4.32x=2.41.8/5x=1/21.8x=2.5x=25/18
(x+1/2)除5/24=8/9除1/6(x+1/2)除5/24=16/3x+1/2=5/24x16/3x+1/2=10/9x=10/9-1/2x=11/18如果本题有什么不明白可以追问,如果满意请点
x除35+2x-4除35-x除28+2x-1除35=12除60x/35+2x-4/35-x/28+2x-1/35=12/60x/35-x/28+4x-1/7=1/5等式两边都乘以7得x/5-x/4+2
原式=[(x+2)/x(x-2)-(x-1)/(x-2)²]÷(4-x)/x=[(x+2)(x-2)/x(x-2)²-x(x-1)/x(x-2)²]÷(4-x)/x=[(
