What value in the replacement set is a solution to this equation?
 
3(n+7)=48
replacement set:   {8,  9,  10}

a: 10
b: 9
c: 8

3(n+7)=48 Replacement set: {8, 9, 10} Drag the solution into the box. ... n = 9 is the value in the replacement set is a solution to the equation ...

Step-by-step explanation:

Well, if you substitute 2 and 6 on the first expression, the answer you get when x=2 is half of what you get when x=6

But for the second expression, the answers are not equivalent
