Answer:

n = 9 is the value in the replacement set is a solution to the equation
3(n+7)=48

Explanation:

Given an equation:
3(n+7)=48 .....[1]

Replacement set: {8, 9, 10}

For n = 8

Substitute in equation [1], we get;


3(8+7)=48


3(15)=48


45=48 False.

Similarly, For n = 9

Substitute in equation [1], we get;


3(9+7)=48


3(16)=48


48=48 True.

for n = 10

Substitute in equation [1], we get;


3(10+7)=48


3(17)=48


51=48 False.

Therefore, the value in the replacement set is a solution to this equation
3(n+7)=48 is, 9
