60(x+3)=60×5+70(x-5-2)计算,60(x+3)=60×5+70(x-5-2)计算,60(x+3)=60×5+70(x-5-2)计算,先拆阔号60x+60*3=60*5+70x-70*
60(x+3)=60×5+70(x-5-2)计算,
60(x+3)=60×5+70(x-5-2)计算,
60(x+3)=60×5+70(x-5-2)计算,
先拆阔号
60x+60*3=60*5+70x-70*5-70*2
移项合并同类项得
60x-70x=-370
x=37
(4/x-5)+(x-3)/(12-x)=(x-45)/(x^2-17x+60)
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
x*x-(x-2)*(x-5)=60
X-60X=5分之3X(怎么解)
4x-3(20-x)=60-5(9-x)
x/70=x/60-5
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
x+2/3x=60 x-2/5x=120 4x+18x=132
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-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
