如果2(x+3)的值与3(1-x)的值互为相反数,求x的值.如果2(x+3)的值与3(1-x)的值互为相反数,求x的值.如果2(x+3)的值与3(1-x)的值互为相反数,求x的值.2(x+3)的值与3

如果2(x+3)的值与3(1-x)的值互为相反数,求x的值.
如果2(x+3)的值与3(1-x)的值互为相反数,求x的值.

如果2(x+3)的值与3(1-x)的值互为相反数,求x的值.
2(x+3)的值与3(1-x)的值互为相反数
所以2(x+3)+3(1-x)=0 .
解方程,得x=9 .
所以,x的值为9

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

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