40.1*(56.32-(X-2.25))=2005 求x=几
40.1*(56.32-(X-2.25))=2005 求x=几

40.1*(56.32-(X-2.25))=2005 求x=几
40.1×｛56.32-x+2.25｝=2005
40.1×｛58.57-x｝=2005
2348.657-40.1x=2005
-40.1x=-343.657
x=8.57
不给分太残忍了,我自己算的阿

40.1*(56.32-(X-2.25))=2005 求x=几 解方程：X+2.25%X-2.25%X*5%*1解方程：X+2.25%X-2.25%X*5%*1=6128.25 X+2.5×2.25％X=56254=X-X20％ 解方程：x+0.7x=2.25 6x×X平方=2.25 求解 2.5%X+(20-X)*2.25%=0.485 x+x*2.25%*(1-20%)=1527 0.75x+0.5x=2.25 (0.5x+1)+(0.25x+0.5)+(0.125x+2.25)=x怎么解, x x X x x x x x x
