Answer:  11

Step-by-step explanation:

The given equation : \(12+(7+m)=30\)            (1)

Using Associative property of addition :

\(a+(b +c)=(a+b)+c\)

We have,

\(12+(7+m)=(12+7)+m=19+m\)                     (2)

From equation (2) and (1), we get

\(19+m=30\)

Using Subtraction property of equality, subtract 19 from both sides, we get

\(m=30-19=11\)

Hence, the value of m=11
