x-6分之5x=10(解方程)-搜答案-灵鹊做题网

5x/(x²+x-6)+(2x-5)/(x²-x-12)=(7x-10)/(x²-6x+8)5x/(x-2)(x+3)+(2x-5)/(x+3)(x-4)=(7x-10)

X/5-X/6=1.4X/30=1.4X=42

x+1分之x+2减去x+3分之x+4=x+5分之x+6减去X+7分之x+8方程两边分别通分,得[(x+2)(x+3)-(x+1)(x+4)]/[(x+1)(x+3)]=[(x+6)(x+7)-(x+8

5x／6=10／21x=60／105=4／72x／7=14x=14×7／2=4945／x=9／14x=45×14／9=70再问：看不懂

由6x^2+5x+(6/x^2)+(5/x)=38移项,同时加上减去12再化简得到：6[x^2+2+(1/x^2)]+5[x+(1/x)]-50=0化简为：6[x+(1/x)]^2+5[x+(1/x)

两边乘x（x-1）(x-1)²+5x²=6x(x-1)x²-2x+1+5x²=6x²-6x6x-2x=-14x=-1x=-1/4在我回答的右上角点击【

(x+5)/(x+4)+(x+6)/(x+5)=(x+4)/(x+3)+(x+7)/(x+6)1+1/(x+4)+1+1/(x+5)=1+1/(x+3)+1+1/(x+6)1/(x+4)+1/(x+5

你好：3x=5分之6x=5分之6÷3x=5分之22分之1x=10x=10÷2分之1x=206分之5x=25x=25÷6分之5x=304分之3x=6分之5x=6分之5÷4分之3x=9分之10

等号前后同时分别计算减法得：(x+1)(x+3)分之2=(x+5)(x+7)分之2所以：(x+1)(x+3)=(x+5)(x+7)x^2+4x+3=x^2+12x+35x=-4

x/(x-5)=(x-2)/(x-6)两边同乘惟(x-5)(x-6)x(x-6)=(x-2)(x-5)x^2-6x=x^2-7x+10x=10检验,代回到方程左边=10/(10-5)=2右边(10-2

因为(x-4)/(x-5)=[(x-5)+1]/(x-5)=1+1/(x-5)……所以原方程可化为1+1/(x-5)-1-1/(x-6)=1+1/(x-8)-1-1/(x-9)1/(x-5)-1/(x

(x-4）/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)对方程两边各自通分：[(x-4)(x-6)-(x-5)(x-5)]/[(x-5)/(x-6)]=[(x-7

x+2分之x+1-x+3分之x+2=x+6分之x+5-x+7分之x+61-（x+2）分之1-[1-（x+3）分之1]=1-(x+6)分之1-【1-(x+7)分之1】从而(x+3)分之1-(x+2)分之

再答：再问：把下面分数化成小数。3分之1420分之138分之12又4分之15分之20

6分之5+x=10分之9x=9/10-5/6x=27/30-25/30x=1/15如果本题有什么不明白可以追问,
