(3000-x)脳60%-200=1/5x
(3000-x)脳60%-200=1/5x
(3000-x)*60%-200=1/5x
1800-3/5x-200=1/5x
1600-4/5x=0
x=2250

小学六年级下册数学解方程.. 要详细的.. 还要过程 都写下来...2x+3x=60 3.6x-2.8x=12 100x-x=198 18x+2x+60 5x+6x=12.1 6.6x-5x=8 4x-x=24 1.5x-x=1 1.9x+0.4x=9.2
(X+X-200)/(X-200)=5
x.x-5x+1=0,那么x.x+1/x.x
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
x(x-1)(x+1)=60
x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x4(x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-1
f(x,-x)=x^2+2x,fx(x,-x)=5x+1,则fy(x,-x)=
60/(1-1/5-X/6)=200x是自然数X=?60/(1-1/5-X/6)X=?
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
