Answer: n = 4

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4 times n which is 4n and 4 times 3 which is 12.

So our equation nor reads 4n + 12 = 28.

Solving from here,

we subtract 12 from both sides of the equation and we have 4n = 16 and dividing both sides by 4, we find that n = 4.
