Question

Please help me!!!!!!!!!

Answer 1

Answer:

11

Step-by-step 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

$\dfrac{2n}{2}=\dfrac{22}{2}\\\\n=11$

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:

$2(12)+5=24+5=29\neq27$

for x = 13:

$2(13)+5=26+5=31\neq27$

Answer 2

Answer: n=11

Explanation:

2n +5=27

2n=27-5

2n=22

n=11
