x-140-(x-140)*40%=1/5x方程怎么做?
x-140-(x-140)*40%=1/5x方程怎么做?
x-140-(x-140)*40%=1/5x方程怎么做?
x-140-(x-140)*40%=1/5x
x-140-0.4x+56=0.2x
x-0.4x-0.2x=140-56
0.4x=84
x=210
x-40%x-140:40%x+140少打了字......x-40%x-140:40%x+140=1:3
解方程 40%x=12 (1+60%)x=24 (1-37.5%)x=10 2x+50%x=20 40%x+30%x=140 35%x-15%x=72
X/5=X/40+140求解
x+40%x=140 怎么解
X/50=X/40+140求解
(X-140)*(1-40%)=1/5X 怎么算!
(X-140)*(1-40%)=1/5X
(1-40%)X+140=1/3X怎么解
0.6x+140 =X
0.6X+140 =X
x+15%x=140
[x-x*(40%)-140]:[x*(40%) 140] = 1:3 ,怎么解
x+(x-140)+(x-210)=270 x=?
x-140-(x-140)*40%=1/5x这个方程怎么做?
x-140-(x-140)*40%=1/5x方程怎么做?
帮我算到数学方程吧X+(1+40%)x80%=x+140把X+(改为X(
六题解方程:x+75%x=140 x-40%x=96 x-76%x=36 4x+50%x=90 60%x-30=120 x+50%x=45
X(X-1)=X
