x分之180减去1.5x分之180等于1分式方程-搜答案-百度作业网

把x移到一边3分之2减3等于8x减2分之1x-7/3=15x/2x=-14/45

(x+1)/(x^2-x)-1/3x=(x+5)/(3x-3)3(x+1)/(x^2-x)-1/x=(x+5)/(x-1)3(x+1)-(x-1)=x(x+5)3x+3-x+1=x^2+5x2x+4=

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

你要说的是：（x+2）分之（x+1）减去（x+3）分之（x+2）等于(x+7)分之1减去(x+6)分之1解方程(x+1)/(x+2)-(x+2)/(x+3)=1/(x+7)-1/(x+6)通分得[(x

2x/5-8/15=4/5×1/22x/5-8/15=2/52x/5=2/5+8/152x/5=14/15x=14/15÷2/5x=7/3

5/（x²+x）-1/（x²-x）=05/x(x+1)-1/x(x-1)=0方程两边同乘以x（x+1）（x-1）,得：5（x-1）-(x+1)=04x-6=0x=3/2

x+2分之1减去x²-4分之4x减去x-2分之2等于x²-4分之x-2减去x²-4分之4x减去x²-4分之2x+4等于x²-4分之x-2减4x减2x-

解分式方程输入很辛苦.经检验X=7/2是原方程的解.

(5/12-1/4）*x=1/31/6*x=1/3x=22/3-8x=x/22/3=8.5xx=1/51

(x-1)/3-(x+2)/6=(4-x)/2等式两边同乘6得：2(x-1)-(x+2)=3(4-x)去括号：2x-2-x-2=12-3x移项：4x=16x=4

(x^2-1)/2-(x-2)/3=x^23x^2-3-2(x-2)=6x^23x^2-3-2x+4=6x^23x^2+2x-1=0(3x-1)(x+1)=0所以x=1/3或x=-1

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

原式,3/5X-1/4=1/3移项得,3/5X=1/3+1/4化简得,3/5X=7/12两边同时除以3/5得,X=35/36

x+4=3x=7

写得有点……希望能帮到你,↖(^ω^)↗

解1题原式=[(x+y)/x]-[x/(x-y)]+[y²/(x²-xy)]=[(x+y)/x]-[x/(x-y)]+{y²/[x(x-y)]}={(x+y)(x-y)/

x/(x-3)-(x+6)/(x^2-3x)+1/x=[x^2-(x+6)+(x-3)]/x(x-3)=(x^2-9)/x(x-3)=(x+3)/x.

X^2/X-2-X/X-2-1+X/2-XX^2-X/X-2-1+X/2-XX^2-X/X-2+1+X/X-2X^2-1/X-2这么简单的题咋能用此乃的口吻～?比我还悲伤

1.x+1分之x-1减去x²-1分之4=x+1分之x+2(x-1)/(x+1)-4/(x²-1)=(x+2)/(x+1)同时乘以x²-1得(x-1)²-4=(x
