To find the equation with the solution n=22, you need to substitute 22 in place of n in each equation and check if the equation holds true.
1) 3n-28 = 38-14
Substituting n=22, we get:
3*22-28 = 38-14
66-28 = 24
38 = 24
This equation does not hold true for n=22.
2) n-15 = 7+15
Substituting n=22, we get:
22-15 = 7+15
7 = 22
This equation does not hold true for n=22.
3) n+16 = 38-15
Substituting n=22, we get:
22+16 = 38-15
38 = 23
This equation does not hold true for n=22.
4) n+16 = 18+20
Substituting n=22, we get:
22+16 = 18+20
38 = 38
This equation holds true for n=22.
Therefore, the equation that has the solution n=22 is n+16=18+20.
Which of the following equations would have the solution of n=22? (1 point)
3n-28=38-14
n-15=7+15
n+16=38-15
n+16=18+20
