Question

解方程（急急急～）

53-2(x+1)=3x+16
我需要详细解答过程，好的加分！

Answer 1

53-2(x+1)=3x+16
53-2x-2=3x+16
51-2x=3x+16
3x+2x=51-16
5x=35
x=7

Answer 2

53-2x-2=3x+16
53-2-16=3x+2x
35=5x
x=7

Answer 3

53-2x-2=3x+16
53-2-16=3x+2x
45=5x
x=9

Answer 4

左边拆开53-2x-2=3x+16即51-2x=3x+16
把数字都放在左边，未知数挪到右边51-16=3x+2x
合并同类项35=5x,
约分x=7

Answer 5

53-2(x+1)=3x+16
53-2(x+1)+2(x+1)=3x+16+2(x+1)
53=3x+16+2(x+1)
53=3x+16+2x+2
53=5x+18
53-18=5x+18-18
35=5x
5x=35
x=7

Answer 6

53-2(x+1)=3x+16
解： 53-2x+2=3x+16
3x+16=53-2x+2
3x+2x=53+2-16
5x=55-16
5x=39
x=39/5
x=7.8
