10^2+(50-x)^2=x^2 x=?我这人懒
10^2+(50-x)^2=x^2 x=?
我这人懒
10^2+(50-x)^2=x^2 x=?我这人懒
10^2+(50-x)^2=x^2
10^2=x^2-(50-x)^2
100=(x+50-x)(x-50+x)
100=50*(2x-50)
2=2x-50
2x=52
x=26
10^2+(50-x)^2=x^2
100+2500-100x+x²=x²
100x=2600
x=26
f(x)=x^2+x (x
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
x+3x+x-2+x+x+50%x=188 求x
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
X+X+X+(X-1)+(X-2)+(X-3)+(X-4)=10(X-3)+(X-4)
x^2+10x( )=(x+ )^2
x^2-10x=2-x
2x×x=10,求x
x^2=x
x+2x×10=10x+2x+36
x-10+X+20+X/2+2X=370
x+10+x-20+2x+x/2=370
(x+1)+(x+2)+(X+3).+(x+50)=1325
x+2x+（x+10）=90,x=?
10x -6.2x-2x=36 x=?
10x+2x*[(50-x)/2]+5x[(50-x)/2]=240
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
