50x(x-1)+60x(x-4)=5100
(4/x-5)+(x-3)/(12-x)=(x-45)/(x^2-17x+60)
X-X/12-X/7-X/8-X/4-X/20-X/5-30-120-300=50解方程
一元一次方程:x-100/50-2=x-100/60+5 x/120-x/130=2 6x+x-1/5+1=100 2x-1/3-10x+1/12=2x+1/4-1
求解下面的一些方程,好的我加50财富啊(170-x)*1/3-1/4x=102/3x+(135-x)*4/5=983x+2(100-x)=3004x-3(20-x)=6x-7(11-x)23-x/x+19=1/5x+180/90=x-180/60
x/50-4=x/60+2 x=?
解方程:60%x+5+50%x-25=x
x-5%x-50%x×60%=36解方程
x+x-60+5分之4x+6=814
4x-3(20-x)=60-5(9-x)
=(x^2-5x+4)(x^2-5x+6) =(x^2-5x)^2+10(x^2-5x)+24 是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=(x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24不好意思我弄错了,是=(x^2-5
=(x^2-5x)^2+10(x^2-5x)+24 =x^4-10x^3+25x^2+10x^2-50x+24 这是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=(x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24
x+2/3x=60 x-3/5x=120 4x+18x=1x+2/3x=60 x-3/5x=120 4x+18x=132!
x+3分之2 x=60 x-5分之3x=120 4x+18x=132x+3分之2 x=60 x-5分之3x=120 4x+18x=132
4x+5=50 x=
x+2/3x=60 x-2/5x=120 4x+18x=132
解方程:4/x-5+ x-5/12-x=x-33/x^2-17x+60thx```````
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
