Answer:

Explanation:

METHOD 1:

Solve the equation:

2n+5=27 subtract 5 from both sides

2n+5-5=27-5

2n=22 duvude both sides by 2

$(2n)/(2)=(22)/(2)\\\\n=11$

METHOD 2:

Put each value from the replacement set to the equation, and check for equality:

for x = 11:

2(11)+5=22+5=27 CORRECT

for x = 12:

$2(12)+5=24+5=29\\eq27$

for x = 13:

$2(13)+5=26+5=31\\eq27$
