Explanation:

the answer is 18

n/2 + 15 = 24

subtract 15 from both sides

n/2 = 9

Multiply both sides by 2

n=18

Answer 2

`\huge\boxed{\sf n = 38}`

Explanation:

Given condition:

`\displaystyle (1)/(2) n + 5 = 24`

• Subtract 5 from both sides

`\displaystyle (1)/(2) n = 24 - 5\\\\(1)/(2) n = 19`

• Multiply both sides by 2

n = 19 × 2

n = 38

`\rule[225]{225}{2}`
