Answer:
n = 4/17
Step-by-step explanation:
3(n + 4) = 27(2n)
distribute thru the parenthesis
3(n) + 3(4) = 27(2n) =
3n + 12 = 54n .....move the 3n across the = sign, and when u move a term across the equal sign to the other side, u change the sign
12 = 54n - 3n
combine like terms
12 = 51n
divide both sides by 51
12/51 = (51/51)n
12/51 = 1n or just 12/51 = n
reduce
4/17 = n <====
and u can check ur answer by subbing it back into the original equation to see if it is true.
3(4/17 + 4) = 27(2*4/17)
3(4/17 + 68/17) = 27(8/17)
3(72/17) = 216/17
216/17 = 216/17 (correct)...so it checks out
