解方程:(x/3)*3m=(1+20%)[(16/3)*m+(21/4)*2m]求x解方程:(x/3)*3m=(1+20%)[(16/3)*m+(21/4)*2m]求x解方程:(x/3)*3m=(1+

解方程:(x/3)*3m = (1+20%)[(16/3)*m+(21/4)*2m] 求x
解方程:(x/3)*3m = (1+20%)[(16/3)*m+(21/4)*2m] 求x

解方程:(x/3)*3m = (1+20%)[(16/3)*m+(21/4)*2m] 求x
(x/3)*3m = (1+20%)[(16/3)*m+(21/4)*2m]
(1)当m =0时,x为任何实数.
(2)当m ≠0时,等式两侧都除以m得
x=(1+20%)[(16/3)+(21/4)*2] =6/5*(16/3+21/2)=6/5*(95/6)=19


(x/3)3m = (1。2)[(16/3)m+(21/4)2m] 求x
xm=6.4m+12,6m
x=19
m为多少对方程均无影响
