x-3/8=1/2-1/5解方程
x-3/8(八分之三的意思)=1/2-1/5 解方程 -
x=3/10+3/8 x=27/40
解:x—3/8=1/2 x=1/2+3/8 x=7/8
x=3/10+3/8 x=27/40
解:x—3/8=1/2 x=1/2+3/8 x=7/8
题目好像打错了,应该是2/3-8x=3-1/2x把如果是这样的话两边同时乘以6 4-48x=18-3x 移项-48x+3x=18-4 合并同类项-45x=14 系数化一x=-14/45
X-3/8=1/2 解;X=1/2+3/8 X=4/8+3/8 X=7/8
x-3/8=1/4解方程? -
45% X -8分之3等于4分之一解方程。
5×8=40,分母都变成40,先变3/8为15/40,1/5为8/40,原题变成x减15/40等于8/40,X等于23/40
x—1/2=3/8怎么解方程 -
x—1/2=3/8 x=7/8
x-3/8=5/12 x=3/8+5/12 x=9/24+10/24 x=19/24 x-3/7=3/21 x-3/7=1/7 x=3/7+1/7 x=4/7 1/4+x+6/7=5/4 x+=5/4 -1/4-6/7 x=1-6/7 x=1/7
x-3/8=5/8+1/2解方程怎样解? -
x-3/8=5/8+1/2解方程这样解:解:x-3/8=5/8+1/2 x=5/8+3/8+1/2 x=1+1/2 x=1.5
(X-3)8=1/2-1/4 (X-3)/8=1/4 X-3=2 X=5
