Which of the following equations would have the solution of n=22 ?(1 point) Responses 3n−28=38−14 3 n minus 28 equals 38 minus 14 n+16=18+20 n plus 16 equals 18 plus 20 n−15=7+15 n minus 15 equals 7 plus 15 n+16=38−15

Answer 1

To find the equation that has a solution of n = 22, we need to substitute 22 for n in each equation and see which one is true.

1) 3n − 28 = 38 − 14
Substituting n = 22: 3(22) - 28 = 38 - 14
66 - 28 = 38 - 14
38 = 24
This equation is not true when n = 22.

2) n + 16 = 18 + 20
Substituting n = 22: 22 + 16 = 18 + 20
38 = 38
This equation is true when n = 22.

3) n - 15 = 7 + 15
Substituting n = 22: 22 - 15 = 7 + 15
7 = 22
This equation is not true when n = 22.

4) n + 16 = 38 - 15
Substituting n = 22: 22 + 16 = 38 - 15
38 = 23
This equation is not true when n = 22.

Therefore, the equation n + 16 = 18 + 20 has a solution of n = 22.
