200*90%+(X-200*80%)=X*85%200*90%+(X-200*80%)=X*85%200*90%+(X-200*80%)=X*85%200*90%+(X-200*80%)=X*85%

200*90%+( X-200*80%)= X*85%
200*90%+( X-200*80%)= X*85%

200*90%+( X-200*80%)= X*85%
200*90%+( X-200*80%)= X*85%
180+ X-160=0.85X
X-0.85X=160-180
0.15X=-20
X=-20÷0.15
X=-400/3

200*90%+( X-200*80%)= X*85% x+50=80%x+200 200-15X=80+25X (1+30%)X×80%=200+X 200-90X=1500-65X x-y=80,x+x-y=200,x等于多少,y等于多少? (60-X)(80-X)=(50-X)2-200吗那你认为（60-x）（80-x）=? (X+X-200)/(X-200)=5 50X=200+X*X 260x=200X(x+6) x+2x-3x-4x+5x+6x-7x.-196x+197x+198x-199x-200x 等于多少解题方法具体过程300+80%×(x-300)>200+90%×(X-200）怎么解 80X-90X=6x+80X 解是几 x/(x+200)=20% x(30-x)=200 X+200X=20010 x+x*2+x/3=200 求x快 200x+50x等于50x平方 x等于
