X＝0.5X-12+0.5[X-（0.5X-12）]+19
X=0.5X-12+0.5X-0.5(0.5X-12)+19
X=0.5X-12+0.5X-0.25X+6+19
移项
X-0.5X-0.5X+0.25X=-12+6+19
0.25X=13
X=52
X＝0.5X-12+0.5[X-（0.5X-12）]+19
X＝0.5X-12+0.5[X-0.5X+12]+19
X＝0.5X-12+0.5[0.5X+12]+19
X＝0.5X-12+0.25x+6+19
X＝0.75X+13
0.25X=13
X=52
x+0.5x＝6
12x-2/21x=快点9点之前还有7x-x+2/3x-3(4x-0.5)-2x+(3x-1)-(x+5)
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=
150.5x －4x ＋0.5x ＝7
x/0.5
-7x(-3)x(-0.5)+(-12)x(-2.6) 计算
-7X(-3)X(-0.5)+(-12)X(-2.6)
(0.2x+0.5)/0.04+(x-3)/0.6=12x
x-0.5x＝3怎么解?
X减0.5X＝10.5
0.3x+0.5（10-x）＝
x＋0.5×x＝22.5
x／3＝0.5十x／4
20%x+12=0.5x
