100-x=88-(50-x) 怎么解~~~
100-x=88-(50-x) 怎么解~~~
100-x=88-(50-x) 怎么解~~~
100-x=88-50+x
-2x=88-50-100
-2x=-62
x=31
100-x=88-(50-x)
100-x=88-50+x
-2x=-62
x=31
100-x=88-(50-x)
100-x=88-50+x
-x-x=38-100
-2x=-62
x=31
日，太简单咯。100－38=2X X=31
100-x=88-50+x
2x=100-88+50
x=31
100-x=88-(50-x）
100-X=88-50+X
100-X=38+X
62-X=X
2X=62
X=31
100-x=88-(50-x)
100-x=88-50+x
-2x=-62
x=31
