(X-24)*(1-40%)=24+(X-24)*40% 要过程.
(X-24)*(1-40%)=24+(X-24)*40% 要过程.
(X-24)*(1-40%)=24+(X-24)*40% 要过程.
(x-24)×(1-40%)=24+(x-24)×40%
(x-24)×3/5 =24+2/5x-9.6
3/5x-14.4=2/5x+14.4
1/5x=28.8
x=144
(X-24)*(1-40%)=24+(X-24)*40%
0.6*(X-24)=24+0.4*(X-24)
(0.6-0.4)*(X-24)=24
0.2*(X-24)=24
x-24=120
x=144
(X-24)*(1-40%)=24+(X-24)*40%
60%x-14.4=24+40%x-9.6
