35道.符号^代表平方.读起来就是（X的平方）.1,x^-x-202,x^-9x+203,x^-9x-204,x^+9x+205,x^-18x+326,x^+14x-317,x^+18x+328,x^+14x-329,x^+19x+4810,x^+47x-4811,x^+13x-4812,x^+2x-4813,x^+26x+4814,x^-22x-4815,x^+17x+7216,x^+21x-10017,x^-x-7218,x
X-35%X=7.8 X+160%X=39
如果X+X+8=35-X,那么X=( )
(x+35)-(x+20)=(x+20)*0.25 现在就要
x-35%x=0.25
x-35%x=39
x-82.5x=35
X+1.5X=35
x(x-35)=150
x-30%x=35
1/2x+35+1/3x+20=x
1/2x+35+1/3x+20=x
35%x=20%x-6 x=?
(35-20)*1.5%*x+x=1323
[35-20]*1.5x+x=1323
(x-35)/9=(x+20)/14
