2x+(36-x)4=36怎么解?
2x+(36-x)4=36怎么解?

2x+(36-x)4=36怎么解?
2X+(36-X)4=36
2X+36*4-4X=36
144-2X=36
2X=144-36
2X=108
X=54

2x+(36-x)4=36
2x+144-4x=36
2x=108
x=54

2x+36*4-4x=36>>>>>-2x+144=36>>>>>-2x=-108>>>>>x=54

去括号,得2x+36×4-4x=36
合并同类项,得-2x=-108
系数化为1,得x=54

2x+(36-x)4=36
X+(36-X)2=18
X+72-2X=18
X=54

2X+36*4-4X=36
-2X+36*3=0
X=36*3/2
X=54

合并同类项得, 144-2x=36
于是移项得 2x=108
解得 x=54
