x+3/2(3x-1)-2/3(4-x)=3/7(x-2)等于多少?

如题所述

x+(3/2)(3x-1)-(2/3)(4-x)=(3/7)(x-2)
解: x+4.5x-1.5-(8/3)-(2/3)x=(3/7)x-(6/7)
(11/2)x-(3/2)-(2/3)x= (3/7)x-(6/7)
(33/6)x-(9/6)-(4/6)x=(3/7)x-(6/7)
(29/6)x-(9/6)=(3/7)x-(6/7)
(29/6)x-(9/6)-(3/7)x+(6/7)=0
(203/42)x-(18/42)x-(63/42)+(36/42)=0
(185/42)x-(27/42)=0
(185/42)x=(27/42)
x=(27/42)/(185/42)
x=27/185
