(x^2-3x+1)/(x^2-4)=30/(x+2)(x^2-3x+1)/(x-2)=30x^2-3x+1=30x-60x^2-33x+61=0x=(33±√1333)/2
(x^2-3x+1)/(x^2-4)=30/(x+2)(x^2-3x+1)/(x-2)=30x^2-3x+1=30x-60x^2-33x+61=0x=(33±√1333)/2
3.5x+x=1.35(3.5+1)x=1.354.5x=1.354.5x÷4.5=1.35÷4.5x=0.3
您好,寒樱暖暖为你5x+40+7x=95212x=912x=76如果你认可我的回答,请及时点击【采纳为满意回答】按钮,(或在客户端右上角评价点【满意】)你的采纳,是我前进的动力!你的采纳也会给你带去财
X加30%X=521.3x=52x=4.
1.1.5x=34.1,x=27.73333333(循环)2.x/3-x/4=0.5所以x/12=1/2,x=6
x-60%x+28=50%x-9x-0.6x+28=0.5x-90.4x+28=0.5x-90.5x-0.4x=28+90.1x=37x=370
x^2+x-1=0(x+1/2)^2=1-1/4x1=根号3/2-1/2x2=-根号3/2-1/2
x平方加X平方分之一加X减X分之一=4(x²+1/x²-2)+(x-1/x)-2=0;(x-1/x)²+(x-1/x)-2=0;(x-1/x+2)(x-1/x-1)=0;
再答:亲!如果满意记得采纳呦!也可以继续问我呦!
x-25%X-(25%x-25)=50x-0.25X-0.25X+25=500.5X=25X=50再问:很快,谢谢你
x+50%x=4.5x+0.5x=4.51.5x=4.5x=4.5÷0.5x=3
2x平方?如果是那解就是x①=-0.027820777536819108x②=-17.972179222463182
x=62x=9x=20x=57x=105x=29x=117x=17x=84再问:还有呢再答:什么再问:就这些吗再答:不然呢
您好:18%X+15=240.18x=24-150.18x=9x=9÷0.18x=50X-35%+1.2=4.7x-0.35+1.2=4.7x+0.85=4.7x=4.7-0.85x=3.85~如果你
x-50%x=150(1-50%)x=1501/2*x=150x=150*2=300
1+1/(x+2)+1+1/(x+3)=1+1/(x+4)+1+1/(x+1)1/(x+2)+1/(x+3)=1/(x+4)+1/(x+1)1/(x+3)-1/(x+4)=1/(x+1)-1/(x+2
解方程x+2分之x-2-x的平方分之16=x-2分之x+2详细步骤加检验x+2分之x-2-x的平方分之16=x-2分之x+2解,得:(x-2)/(x+2)-(16/x^2)==(x+2)/(x-2)(
x/2+x/6+x/12+x/20+x/30=5x(1/2+1/6+1/12+1/20+1/30)=5x(3/6+1/6+1/12+1/20+1/30)=5x(4/6+1/12+1/20+1/30)=
