如何解方程式X-1/4X-(1/4X-4)=50如何解方程式X-1/4X-(1/4X-4)=50如何解方程式X-1/4X-(1/4X-4)=50X-1/4X-(1/4X-4)=50x-1/4x-1/4

如何解方程式X-1/4X-(1/4X-4)=50
如何解方程式X-1/4X-(1/4X-4)=50

如何解方程式X-1/4X-(1/4X-4)=50
X-1/4X-(1/4X-4)=50
x-1/4x-1/4x+4=50
1/2x=50-4
1/2x=46
x=92

x-1/4x-1/4x+4=50
1/2x=46
x=92

先把括号去掉,得X-1/4X-1/4X+4=50,加减运算得
X-1/2X+4=50,
1/2X+4=50,
1/2X=46,
X=92。

(1)X-1/4X-1/4X+4=50.(2)1/2X=50-4.(3)1/2X=46.(4)X=92

x-1/4x-1/4x+4=50
1/2x=46
x=92

x-1/4x-1/4x+4=50
1/2x=46
x=92

首先,去括号。
x-1/4x-1/4x+4=50
合并,得.
x-1/2x+4=50
移项,得
x-1/2x=50-4
合并,得
1/2x=46
系数化为一,得
x=92

已知X-1/4X-(1/4X-4)=50 得知 X-1/4X-1/4X+4=50 得知 1/2X=50-4 得知 1/2X=46
得知 X=92
