Which of the following equations would have the solution of n=22?

Question

1. n−15=7+15

2. n+16=18+20

3. n+16=38−15

4. 3n−28=38−14

Answer 1

Let's solve each equation:

1. n-15=7+15
n-15=22
n=37

2. n+16=18+20
n=22-16
n=6

3. n+16=38-15
n=7

4. 3n-28=38-14
3n=52
n=17.33

Therefore, the only equation that has a solution of n=22 is option 2: n+16=18+20.
