(X-240)×60%=X-1400解的步骤

(X-240)×60%=X-1400解的步骤
(x-240)x0.6=x-1400
0.6x-144=x-1400
0.6x= x-1256
0.4x=1256
x=3140

换算成(X-240)×0.6=X-1400
0.6X-144=X-1400
-144+1400=X-0.6X
1256=0.4X
X=3140

60%x-240*60%=x-1400
60%x-144=x-1400
1400+144=x-60%
1544=40%
x=1544除以40%
x=3860

0.6x—240*0.6=x—1400
0.6x—x=144—1400
—0.4x=—1256
x=314

6x-1440=10x-14000
4x=12560
x=3140
