Question

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

Answer 1

9

Explanation:

Answer 2

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
