解方程:2y-1/3-1=5y+1/8-3y+1/6加括号(2y-1)/3-1=(5y+1)/8-(3y+1)/6解方程:2y-1/3-1=5y+1/8-3y+1/6加括号(2y-1)/3-1=(5y

解方程:2y-1/3-1=5y+1/8-3y+1/6加括号(2y-1)/3-1=(5y+1)/8-(3y+1)/6
解方程:2y-1/3-1=5y+1/8-3y+1/6
加括号(2y-1)/3-1=(5y+1)/8-(3y+1)/6

解方程:2y-1/3-1=5y+1/8-3y+1/6加括号(2y-1)/3-1=(5y+1)/8-(3y+1)/6
方程中y被消去.所以y可以是任何数.

一个个的折开来,很容易的了,

16y-8-24=15y+3-12y-4
y=31/13

(2y-1)/3+2(3y+1)/3-1=(5y+1)/2 [(2y-1)+2(3y+1)]/3-1=(5y+1)/2 (2y-1+6y+2)/3-1=(5y+1)/2 (8y+1)/3-1=(5y+1)/

去分母,得8(2y-1)-24=3(5y+1)-4(3y+1)
16y-8-24=15y+3-12y-4
13y=31
y=31/13
