4n + 8 = 20Which value of n from the solution set 3, 8, 10, 12) will make the equation true ?

Brilliant_brown [7]

The value of n from the solution set is <u>3.</u>

<u>calculation:-</u>

⇒ 4n + 8 = 2

⇒ 4n = 20 - 8

= 4n = 12

= n = 12/4

⇒ n = <u>3</u>

Therefore, from the given set 3,8,10,12, the value of n will be 3.
