如果2(x+3)的值与3(1-x)的值互为相反数那么x等于
如果2(x+3)的值与3(1-x)的值互为相反数那么x等于

如果2(x+3)的值与3(1-x)的值互为相反数那么x等于
2(x+3)的值与3(1-x)的值互为相反数
∴2(x+3)+3(1-x)=0
2x+6+3-3x=0
9-x=0
∴x=9

9

2(x+3)的值与3(1-x)的值互为相反数
2(x+3)+3(1-x)=0
x=9

x=9

2(x+3)+3(1-x)=0 2x+6+3-3x=0 -x=-9 x=9

x=9

2(x+3)的值与3(1-x)的值互为相反数
2(x+3)+3(1-x)=0
2x+6+3-3x=0
2x-3x=-6-3
-1x=-9
x=9
