4x+2=39+3x哪位好心人能帮个忙啊
4x+2=39+3x哪位好心人能帮个忙啊

4x+2=39+3x哪位好心人能帮个忙啊
4x+2=39+3x
4x-3x=39-2
x=37

x=37

4X+2=39+3X
4X-3X=39-2
X=37

4X+2=39+3X
4X-3X=39-2
X=37
验算：
37*4=148+2=150
37*3=111+39=150

4x+2=39+3x
4x-3x=39-2
x=37

4x+2=39+3x
4x+2-3x=39
x+2=39
x=39-2
x=37
好久没做不知道对不对。

4x+2=39+3x
解:4x-3x=39-2
x=37
