(x+30)*62.5%+240=(x+30+240)*75%过程
(x+30)*62.5%+240=(x+30+240)*75%
0.625(x+30)+240=0.75(x+270)
0.625x+18.75+240=0.75x+202.5
0.75x-0.625x=18.75+240-202.5
0.125x=56.25
x=56.25÷0.125
=450
(x+x)+(x-x)+(x/x)=11.2
(x+30)*(x-18)=x*x
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
x - 3/5x = 240 - 30 - x
24-X=62.5%(30-X)

(25-30)*1.5%x+x=1323 x=?
(30+x)/(70+x)=3 x=
45X=(4-X)*30 X=1.6
2x(56-X)-10=30+X

(30-x)+x+(25-x)=50求过程,
(X-30)/X=45/100 求X
240-x=(260-x)*80%
240-x=(260-x)*80%
先观察下列各式,(x+5)(x+6)=x²+11x+30 (x-5)(x-6)=x²-11x+30先观察下列各式,(x+5)(x+6)=x²+11x+30(x-5)(x-6)=x²-11x+30(x-5)(x+6)=x²+x-30(x+5)(x-6)=x²-x-30(1)乘
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
x/(x-8)=30/15
