X-0.5X-12-0.5(X-0.5X-12)-8=18
0.5x-12-0.5(0.5x-12)=18
(1-0.5)(0.5x-12)=18
0.5(0.5x-12)=18
0.25x-6=18
0.25x=24
x=96

少米X-0.5X-12-0.5(X-0.5X-12)-8=18 X=128m 128米

0.5X+120+0.3X=X 4X+0.5X=13.5X x-30-0.2x=0.5x x-0.3x-0.5x=20 9x+0.5x+x= 12x-2/21x=快点9点之前还有7x-x+2/3x-3(4x-0.5)-2x+(3x-1)-(x+5) x/0.5 求x:|x|-|x-4|=0.5x-1 X+0.5X=3 X-0.8X=8 250x - 2(x+50)(x+0.5)求x x/0.5+(60-x)/8 x+0.5x=30 X=12.8+0.5X x-0.5x=20, x+0.5x＝6 0.5X=X-9 60x+40*(x-0.5) x-0.5x=1.3
